Problem: Calls are at random forwarded to voicemail!!

Hi Guys,
Since a week or so calls are at random directly forwarded to my voicemail.
I have checked my "call forwarding" settings and they are normal:
Forwarding is enabled if I don`t answer after 25 sec, when I`m unavailable and when I`m busy. After a couple of hours I recieve a sms that I have messages waiting in my voicemail. This happens totally at random because a couple of hours later the same people can reach me without any problems
I am assuming that my phone sometimes loses connection to the T-mobile network and so I am unavailable and the call is forwarded to my voicemail. The reason why I assume this is because don`t see a missed call on my phone. I have never had problems with dropped connections nor noticed that I connection is lost. .
Only thing that I recently changed was upgrading my rom to Molski.Biz Rom (RUU_Molski.Biz_226102_22610105_022511_WWE ) on 2 october but I only noticed the problems about a week, so I don`t know if it can be related. I also upgraded to the 2.47.11 radio ROM to see if it would help but without difference so I reverted back tot the 2.25.11 radio ROM
I called T-mobile and they told me it must be related to the phone and couldn`t be a problem with different carriers nor the T-mobile network.
Has anyone have had these problems? or knows a sollution to this?

Edit: running software: Agenda Fusion, Photo contacts and handyswitcher and I don`t have GPRS programs running.

I guess you are losing the connection. You should look for some sort of a pattern? What seems to be random may not be random at all.
Also... You still get SMS for voicemail notification? That's some deja vu...

What software do you have installed that might go out to the internet from time to time? Do you have an email account setup where it will check every 15 minutes?

I don`t have any software that is using the internet on my phone! So that can`t be the problem.
I haven't noticed any pattern in the forwarding or losing my connection. It is happening on different times of the day. It always happens in standby modus of the phone but I do recieve the SMS for voicemail notification but sometimes 3 hours later, so it could be that the connection was lost during 3 hours?

I think i have the same problem. It happens not very often (i think) but its very annoying.
I also found out that my problem is only related to inbound calls.
Cos I was able to place an outbound call with my wizard but i couldnt call it using another phone. It just switches immediatly to voicemail and indeed after a few hours the inbound connection comes back up again and the voicemail-notices start coming in.
I've had numerous calls with the T-mobile helpdesk about this and they also said it was probably phone-related.
Not looking forward to send it off and live without my baby for a cple of weeks
Oh by the way I have rom:2.26.10.2 WWE

I also noticed today that`s only inbound! Today a buddy of mine was calling me while in front of the door. So we tested it right away. He called me again and I also called with my home phone to my mobile and both times directly the voicemail.
Strange thing was that the whole time I had connection with the T-Mobile network with 4 stripes network strength, so the connection wasn`t lost but I was unreachable. At the same I could place a outbound call without any problems.
Is this still phone related?
Full strength connection with T-Mobile network and only inbound calls blocked, outbound no problemo. I don`t get it anymore!

maybe try a different radio and see if that helps the problem.

The threadstarter allready tried another radio, i don't know if there is newer one. I would gladly give it a try.
My wild stab in the dark would be that something goes wrong when moving to another gsm-antenna (location)
Somehow the phone is not reporting as available or something.(i have no clue about gsm technology so never mind )

Heej there,
got exactly the same thing over here since I've upgraded to Molski's Rom 2261002nld. Also updated to radio 24711 but it didnt change.
I'm now flashing it back to tmob 2210205 to see if it's ok now....
I'll keep you informed...

Is this just a Dutch problem? I'm thinking it is more of a network problem despite what T-mobile.NL are saying.
Does the problem occur at peak times?

I have a similar problem. I was getting Voicemail notifications without the phone even ringing. Then i ran into someone and they said they called several times and i never answered. So I called my own phone and takes my phone 4 or 5 beeps for it to ring.
I'm on shogun and faria's cingular 2.26rom i also have photo contacts on.

Problem Solved
I had the same problem (also with T-Mobile Dutch by the way) with the 2.26 rom until I downgraded my radio rom to 02.07.10. All is fine now.

I also have the same problem. Using 2.26 dutch rom

same problem
I have the same problem after installing the new Molski 2.26.10.2 AKU2.3 Rom.

I have the same problem
t-mo 2.26 WWE

Same problem here only with Jester rom Aku 2.3 and T-mobile dutch

Well, I still have the problem about every other day.
And yes. I'm in the Netherlands.
I'm considering returnung it to t-mobile because i cannot trust my phone anymore. It sucks

Hello,
As far as I know (and our Orange's contact has confirmed us this issue), active GPRS data connections make incoming voicecalls to be redirected to voicemail. This doesn't happen if your device is GPRS-attached to the network but not trasmitting/receiving any data at the moment the call is produced.
This effect has become more noticeable since new devices implement DirectPush, so they are permanently updating info from the exchange server.
I'm sorry, the only solution I know for this is to use a 3G/UMTS device, which enables true simultaneous voice and data connections.

Got the same problem. It seems only to occur on the T-mobile Dutch network. I'm running Molski's rom and tried both 2.25.11 and 2.47.11. I don't think it's a gprs issue, because there was no gprs connection when it happened. Also no active programs that use gprs.
Didn't have the problem at all with the latest dutch T-mobile rom.
I just flashed my radio rom back to 2.19.11 from the original rom. I hope it will solve the issue.

Rectification
Hello. I asked again my Orange's contact person and it seems that what I said wasn't very precise in the sense that voicecall redirections occur only under specific circumstances like channel congestion on the network's cell. Normally voice has priority over GPRS and it can 'steal' radio channels from active data sessions so the bandwidth is reduced. But it shouldn't allow to steal the last channel if it was busy. Maybe in this case an incoming call could be redirected to voicemail.
Of course, a problem with a specific rom version and its radio interface could be a problem. I'm sorry if my contribution should blurr your insight into the problem.
I will ask network engineers to learn more details about this issue.
Bye,

Not receiving phone calls?

Hello all,
I have had my X1 for about a month, and it seems I've come across a problem that defeats the purpose of a phone. I can't seem to receive calls for some reason...recently my friends and family have been telling me they have tried to call me but it just ends up going to my voice mail. I just tell them I was probably on the phone with someone at that time, or my phone was off. Only today did my friend call me to find me in a parking lot that I finally realize its my phone. So I attempted to call myself with my homephone, and tada! it went straight to voicemail. I don't even get any sign of a missed call.. Did anybody else getting this problem? I did a soft reset and it seem to fix the problem. It has probably happened within the past 2 weeks..I have the generic UK rom so I'm still waiting for the official R2A one. It would be great if someone could explain how to prevent this problem from happening.

not that i have a problem with my x1a, mostly because i rarely get calls and rarely use it but i have another phone that would have a problem that you describe.
i think it was due to the phone switching between 3g and edge signal. i work in the ship yard and the steel walls around the ship interfere with my signal and my phone would switch back and forth between getting the best reception (3g and edge).
well anyways, i think the switching back and forth would somehow screw my phone up and i wouldnt get any calls after getting off work.
my brother who also works at our shipyard and carpools with me would try to call me up to ask me if i was getting off in time but i wouldnt know that he had been trying to call me untill we meet up. he tells me that he has been trying to call me and so as were walking back to the car, i asked him to call me to see if my phone is working.
sure enough, my phone doesnt work untill i turned it off and then turned it back on. so if your in an area with poor 3g reception, maybe that could be causing your problem.
my old phone was an old lg cu500. thats my beater phone and since i dont use it for browsing the internet anymore, i set it and leave to use edge. it gets a stronger signal than 3g but if i do need to use 3g, i just go to my phone settings and set it back to use both signals. for some reason, i almost love that beater phone more than my xperia. mainly because its small, compact and i dont have to worry about scratching or damaging it anymore.

hmm, that is rather interesting...however my service provider's 3g frequency band is not compatible with the x1. I also don't have an internet service type of plan with my phone.
However just going to my settings, I noticed that my phone was set up to attempt to connect to the internet via HSDPA. I'm going to disable it and see what happens.

if you dont have 3g or hsdpa connection, then i would set your phone to use only gsm.

I also miss most of my calls but my problems is other some times it rings and some times it doesnt. Anybody know how to fix this?.

I have seen these problems with another PDA, in that case it seemed to be related with the PDA radio at the beggining, but even if that is one of the probable causes, there are another two to be considered.
The first one is the sim module, I own the same sim since 6 years ago, and this sim was programed specifically for the symbian phones of those years, it is in fact unable to send/receive any MMS with a PDA.
The other PDA I'm talking about is an Universal, the same phone worked ok with my sim and failed to receive many calls (even if the covering of this phone company was "better") -in the same place- with the universal, We first suspected a broken sim, but using this sim in a old gsm phone, it worked just fine.
Also, the cell companies, tend to "abuse" of their position and then to "seed" the phones with applications that do use the phone automatically, these programs are made mainly for symbian phones.
Remember also that the cell networks are exactly that, computer networks, and sometimes their databases are not perfectly compatible with all the possible variations of slightly different phones, in this case, PDAs are the least common type of phone.
So, try your phones with other (another cell company) sim, try using the sim with old phones, etc.
hope this helps.

Making calls unreliable on 3G (UMTS/HSDPA) while on AT&T

I was thinking of posting this in the general section but posting it here seemed more appropriate as I think the issue at hand is of a more technical nature. If this is not the case I apologize in advance.
I recently purchased a Black HTC Magic (Rogers branding) for use on the AT&T network here in the states. Since then I have had a very difficult time initiating calls while connected via 3G (UMTS/HSDPA). Even in high or low signal situations.
Unfortunately there doesn't seem to be any consistency to my ability to make a call while on 3G. At times 5/5 calls would be successful and other times 1/5 calls are successful (the latter being true more often than not).
Suspecting there was some issue with my device being on 3G I forced my device to use 2G (EDGE) connections only. At which point my reliability issues go away completely (from what I can tell).
I don't experience any strange issues with using my data connection while on 3G/2G so it seems to be specific to voice.
Another interesting thing to note is while trying to initiate a call with the Google Voice application on 3G, I experience the same call initiation issues as mentioned above. Google Voice works as expected while on 2G.
I experience these issues on the original shipping Roger's ROM, as well as all the other 3rd party ROMS (HoFo, Cyanogen, etc...)
Here is information about my device from fastboot...

Is it possible that my SIM card may be causing issues?
Anyone else with a North American Magic experiencing issues on AT&T? I appreciate any help you guys could provide.

your phone is ok
perhaps you might have heard... iphone great phone...AT&T absolute **** network
with dropped calls, and constant diverts to voice mail. dont sweat it. its AT&T not
your mobile.

I would have to agree that it's probably the network, although I might be wrong. I also have a Rogers Magic running on AT&T in Arizona, and I have this issue as well, but not nearly as frequently as you do. This same problem used to happen from time to time with my HTC Fuze and my BlackBerry Curve.

I've had a variety of different devices on the AT&T network (Northeast/Washington, D.C) and although yes I have experienced AT&T's wonderful network. What I'm experiencing just doesn't seem right. Makes me wonder if it's my SIM or particular build....

MOD EDIT
Moved into general discussion forum as not related to android development

if you are not using a newer sim card i would start by changing that. i was using an older 3g sim which i have used with many phones and i found that by changing to a brand new sim the few connectivity issues i had have gone away

which ROM?
Just a question, but which ROM is everyone here using? I, too, experience the random inability to make phone calls over HSDPA. I was told by an at&t rep in-store today that the Rogers Magic does not 'show up' in their system as 3g capable. Pure bs is what I think, but lets rule out software, yes?

If it is not your sim card then it is most likely your network.

Calls over 3G/HSDPA is fine on my Magic and was also fine on my Nokia N79 using the same Cingular SIM card that I have. However, making outgoing Google Voice calls over 3G/HSDPA is a no go.

Yeah...making calls was fine on my Unlocked Touch Diamond, too...but it's NOT on the Magic (32a).
SO...I'd just have to guess that it's *probably* not the SIM card.
I was told (via an exceptionally helpful phone rep) that the "voice 3g" in my area is not very good, but that the "data 3g" is much better. Which (she says) is why I have trouble making phone calls, but that data works fine.
I don't think so...but without *that* answer, I'm left with the AT&T stock "well, we don't support *unlocked* phones, sir, we can't guarantee that they'll work with our network".
ARRRRRGH! REALLY?! SO, phones with the same chipset, using the same technology won't have the same results?
PLEASE, FCC, INVESTIGATE THIS B.S!

Hey radikaled, I have some new developments with GV and outgoing calls. If I set the GV call options to "ask for each call" the issue of calling over 3G appears to be alleviated somewhat. Basically, when initiating a call, you will be prompted on whether you'd like to make the call via GV or not. At this point, wait a few seconds at this prompt and then choose GV. So far the call has successfully connected 100% of the time.
It appears that the data connection is too slow to establish fully over 3G, therefore, the call fails if you don't wait the few seconds before choosing to call via GV.
Let me know if this works for you.

I too had issues with my ROgers Magic unlocked on ATT. When I first got it I used the original ROM and then the HoFo ROM. Both had similar issues with dropping calls when switching from EDGE to 3G and back. I also dropped more calls than normal.
I recently switched to Cyanogens ROM and new radio. I have not had any issues since and then. Calls and switching is very stable. Also the clarity and volume is also much better. Just my experience. Very pleased with this phone on ATT now.

Thanks for sharing your experience. May give CM ROM a shot.

Good read.
Nice post. Interesting topic.
I tried to send several other users your way...I'm sure they eventually checked this out. I've come across this issue with some other folks recently too.
Best of luck though.

Me TOO!
I also have a similar problem. When connected with HSDPA, about one third of the calls I make fail immediately, even with full signal strength. I then wait a few seconds and dial again, and it works. I actually am using the sim card from a previous nokia POS phone I had from two years ago; the ATT people just took it out of the previous crap phone and put it into my poor fuze. How much does a new SIM card cost? Can I get a new SIM card without att bothering me about not having the stock rom? I'm using Da_G's clean fuze 23008 winmo 6.5 with the 1.12.25.19 radio. I live in the Youngstown, Ohio area (between cleveland and pittsburgh), so cell reception on any network is pretty bad, but it seems the ATT/cingular network around here is particularily bad. Any ideas?

Missed calls despite good signal

Hi,
Just got the Galaxy S, im on orange and im finding that the phone is going straight to VM even with full signal, this seems to happen about 80% of the time, i get a message straight after saying i have a missed call. It seems to be worse when its in my pocket, i had a similar issue with my nokia 5800 but not as bad, i just thought it was the phone getting old.
I have a new sim but same number etc.
Anyone else having similar issues?

I had the exact same thing on mt old i8910hd on orange.I put it down to the fact the phone had a few knocks but who knows? Hasnt happened once on galaxy s with vodafone

Also on Vodafone, not encountered this problem yet.

You may have to consider that this is a problem with your provider. In the netherlands, tmobile had an issue with this due to an overloaded network. Since you live in london I guess that would be a likely reason (tmobile mainly had issues in crowded areas). My suggestion is to try and disable your 3G connection and see if that makes a difference. Here people couldn't receive calls when their 3G was on but when they turned it off, the problems seemed to disappear.
If this works for you, you may want to contact your operator. The sounds to me like it isn't a device related issue.
Sent from my GT-I9000 using XDA App

Thanks for the reply, stepping down to 2g did seem to help, i have found some other posts on other forums, one forum suggests that orange are aware of the issue, lets just hope they resolve it soon.

I had this problem with orange at least 8 months or so, so i wouldnt hold your breath

Not receiving incoming calls when 2G/3G etc connected

The other day one of my friends told me that when he rings my phone lately (since I've started using Android) it always diverts to my voicemail. I did a bit of testing, and figured out that is seems to be happening when 2G/3G data connection is active. Has anyone else had this problem, and can a few people test this out?
I've tested this with 2 radios:
Leo_RADIO_2.12.50.02_2
Leo_RADIO_2.07.51.22_2
and 2 android builds:
30.08.2010¦ ?shubCRAFT 1.5?CM6 Final?¦ ?Kernel: ElBartoME 2.6.32.9 #1? ¦
New Nexus One Android 2.2 Build FRG33 [ mccm v1](5.9.2010)
I have tested on WM and this problem isn't happening there. I am on O2 UK Post Pay.

I have this problem and it happens when my phone is sending/receiving data, not when the data connection is idle. It happens on WM, Android, and on my iPhone too. My provider says this is normal and nothing can be done.
Sent from my HTC HD2 using XDA App

Switching from 2.12 radio to 2.10 in my sig helped this a lot.
Sent from my HD2 mattc froyosense using XDA App

I gave 2.10 a go, but it seemed to make little difference for me.

I had the same problem with the 2.12 radio. I wouldn't get any calls from sprint users.

This is normal with GPRS aka 2G. It's like you go online with a modem and a phone line in the old days (dial-up). Even when you are trying to send a txt, and a call come in at the same time, the text sending will fail. This is very annoying.
not sure about 3G tho, some say that the 3G can handle data and calls at the same time.

I get this too, Plus when i recieve a call i cannot hear the caller for 10 seconds or so ? but the caller can hear me straight away ?
I did post this in the HD2 general thread but got no responce...
Have changed sim card as i was told this could be the issue but no luck also tried various radios/Builds inc android again with no luck..
Looks like were gonna have to live with it

GPRS/Edge does not necessarily allow simultaneous voice
Well I had no idea. I thought that one of the main advantages of GRPS/Edge was simultaneous voice and data, but I guess not. Apparently it is dependent one the cellular network configuration/capacity.
Here's an MSDN article related to it (not that I consider MS a reliable source of anything, but worth a read )
http://msdn.microsoft.com/en-us/library/bb416348.aspx

I had this exact problem. For me it started after using android on my HD2 then whenever i had my phone on UMTS i could call it with another phone and 4 times oout of 5 i would ring all the way to voicemail and never notify me. I first thought it was ATT but i tested my sibling's phone and it was fine, i even switched SIM cards. the problem seems to have gone away with my HD2 after two weeks however I ended up ordering a telus desire with ATT bands. Although now my HD2 reboots in android randomly whenever using UMTS data.

This is what I get as well, except the caller doesn’t hear me for 5 secs or so. I end having to say “hello” 3 times before they can actually hear anything and by that time they usually hang up. I’ve had this problem with WinMo as well, using Telstra on Rogers. It’s kind of annoying since I end up having to use daytime minutes to call them right back.
I found that some x.51.xx radios helped but Android as far as I know is only compatible with x.50.xx radios. So hopefully a new radio will help with this though I’m not really counting on it.

I thought I was going mad
I have the same problem but only just found out. I use my Google navigation a lot, but just discovered when I do that incoming calls are routed to voicemail. I have tried 3 different Radio's from the recommended Leo_RADIO_2.15.50.14 down to 12 and even 08 nothing seems to work.
I have also tried different ROM's from HD Desire to Gingerbread, again no difference.
Not sure if the problem existed on the SD ROM's but it is sertantly an issue on the NAND ROM's.
I am using RMNET as this is the only one that seems stable on O2 in the UK.
This problem is driving me crazy.
Someone else please HELP!!!!
