Dunno what is going on here - I had this problem occasionally with E200 / C500 on Orange, but not to this extent.
Sat at my desk, I suddenly get a Voicemail notification. Strange, as the phone hasn't rung. So I decide to test it.
I get NO ringtone on the phone I'm calling from. Nothing at all. Then it cuts straight to VM. (Phone is sat with full signal, and connected to UMTS network). I phoned 5 times, all with the same result.
Then I hung up the UMTS. Same thing happened.
I did a soft reset and left it in clamshell mode, and phoned again. This time I could clearly hear the ringing on the phone I was calling from, but the device didn't ring / vibrate or anything.
I opened it up and had a message "The phone operation failed" so I hit OK on this and closed it back up again. Phoned it again and this time it rang properly. I hung up before connecting, and got the "Missed call" notification.
Its not (entirely) down to being connected to UMTS - as my phone reconnects automatically as soon as it starts up.
Anyway, having dismissed the "You have a missed call" notification, I tried again. Its back to its original state now, no ringing heard on the phone you call from, and nothing on the phone itself. I only got ONE missed call notification, despite calling it around 7 or 8 times in all.
What the hell is going on here? It almost seems like the phone itself signals to the network that it is totally unreachable (hence no ringing heard by the caller).
I assume you haven't set up diverts or anything?
Get your network provider to do a test and see if they can give you any further information.
Failing that, it's possible that if you stopped the ExtROM from fully installing, it could be causing problems? Or maybe even some sort of task manager may be 'killing' the phone services?
I hadn't set any diverts, and it was the oddly random nature that was cause for concern - it worked after the soft reset, but didn't work beforehand. I can't be doing with a phone that, for its own reasons, refuses to aknowledge an inbound call! This should take precedence over anything else the "phone" is doing at the time, surely...
I've got T Mobile to send me out a reset of my profile (a text message which I delete, then power off the device) and I'll see how it goes.
I did have SBP PocketPlus installed, but no longer... I've not got much installed at all, at the moment.
Strongly considering flashing to the iMate ROM at this moment!
After removing the battery I retested. It was fine.
After writing the last post, I retested again and its broken again.
B*llocks.
The same as you my XDA Exec, oftern misses calls, ( you ring your self and hear it reing bu the phone makes no noise) i also had the same on my XDA2i, and yes removing the battery fixes it for a while.
Also mine when it looses service ( witch is oftern ) it will not go back into service until i soft reset it

Hmm, sorry no clue.
I have a JasJar and no-one has told me off for missing their calls. (I take quite a few from work, but rarely make any myself)
Maybe try a ROM flash, but I'm sure other Exec users are not having these problems, so it sounds like it might be something other than a ROM issue?
I've just stuck the iMate Rom on it. Was probably going to do it anyway, but didn't want to break my TomTom setup...
I'll do some testing and will repost on this thread with my findings.
I'm still getting the problem with the iMate ROm installed.
When I go to the Phone settings, it thinks I'm on the UMTS T-Mobile UK network. Now I'm sure this is fine for data, but maybe its not OK for voice, or something like that?
Can anyone let me know what they have in those settings?
Spotted this too on the Jasjar - can't pin down why though as it only appeqars to have started recently

I'm becoming certain that my data connection is effectively hogging the phone and not allowing voice traffic. I just had problems sending a text message. Every time I hit send, it failed (about 6 times) and went into drafts. To get it to sent, I hung up my active data connection and tried again, and it went immediately.
This is a nightmare, as the device HAS to perform both voice and data functions. I want an always-on data device, but the data MUST be interuptable by inbound / outbound phonecalls as well as notifications (SMS etc).
Right...
I've dropped down to GSM instead of 3G by removing the "Auto" setting from the Band option within the Phone Settings. This appears to have solved the problem.
From looking at the network, it appeared my phone was always connecting to a network called "UMTS T Mobile" (this was even displayed on the occasional incoming call that worked as the carrier). I'm certain this is what is causing the problems. After a Soft Reset, it would still connect to this, as my OTA ActiveSync connection would start up...
Having changed to GSM instead, I'm now connecting to "T Mobile UK" as my carrier - and this is allowing full inbound/outbound functionality - albeit only with GPRS data connectivity.
I'm on T-Mobile UK, and MSN Messenger will happily be interrupted when I get a voice call?
I'm lucky enough to live and work in an area where I'm only ever connected to UMTS (although the setting on my phone is "Auto"). I'm 99% certain that I can get calls every time, and having tested it just now a couple of times it's working without any problems, so there must be something that'll sort out your problem?

I'm lucky enough to live and work in an area immediately covered by whatever equipment may (or may not) be located a T Mobile's head office... :roll:
I cannot discount the possibility that they've erected a UMTS cell which they "tinker with", which may (or, indeed, may not) be causing my problems...
I guess next time I'm out of the area, and in a 3G coverage area elsewhere, I will revert and test it.
In the meantime, they've asked me to test by switching back to "Auto" and trying to phone my phone once in a while, taking note of when I call and whether I get through, and they'll endeavour to trace those calls and find out what is going on...
I hope you'll be sending them an invoice!?!
I have this problem now. I only noticed it after a ROM upgrade (to the latest TMUK ROM). What fixed your problem in the end?
Hi All
I have had a very similar problem and have been discussing it in a separate thread.
http://forum.xda-developers.com/viewtopic.php?t=62863
As you will see, it seems to me that it is a T-Mobile issue, but they don't acknowledge that it is a fault. I don't get the same problem when I put an O2 sim in my Exec.
Other than downgrading to GPRS, I don't think there is any fix.

Mark, I've had a thought. Do you (like me) have an old 5v T-Mobile SIM.
These SIM’s can be identified either by SIM serial number 893044 05 or 16 – up to and including 893044 50. SIMs with serial numbers 893044 52 and above will be ok- anything lower is likely to be a 5v.
There was an issue when I 1st got my MDA Pro. It had to be network unlocked by T-Mobile for it to work with my SIM. Is it possible that the ROM update as "re-awakend" this problem?
(Also posted in thread you link to)
Thanks for the idea, Slave1, but I don't think that is the cause of the problem. My SIM doesn't have a serial number anything like those you suggested (it starts 060080...) and I only got it a couple of months old and so I am sure that it is a 3G one.
However, now that you mention it, I did have a problem getting the SIM to work when I first got it. I had to get on to Customer Services to get them to register it on the network becuase, they said, the shop hadn't registered it correctly!

All SIMs are usable with 3G (it's the handset that make the difference)

That's a different issue but just as frustrating.
I had another though. Is anyone using a T-Mobile SIM in an XDA Exec (or just using an O2 ROM) having the same problem?
Could it be a ROM issue?
I upgraded to 2.24 Tmobile official beta ROM. and it seems that I cant get phone calls while im streaming thru EDGE/GPRS not just streaming also like browsing and stuff, phone calls go straight to voicemail, is this how it was on 2.17 or 2.21 ? Because I tought it worked before !!!! Can anyone confirm please...
Can some one please verify regarding this, can some one just try browsing somethign and call them selvs and see if it goes straight tru to voice mail on a diffrent ROM please....
Yozh:
I had an 8125 on the Cingular network running Summiter's 2.17 ROM, and the phone call always interrupted any web surfing I was doing, and/or disconnected IM+ (which uses gprs/edge).
That phone broke (d'oh!) and I got another one that was running the stock ROM. Same thing.
I now have a new 8125, and just upgraded to Summiter's 2.3 ROM (thank you Summiter!), and the phone acts the same.
I've never experienced an issue where the phone call goes directly to voice mail... that I know of.
Very strange, I tought thats what mine used to do before the 2.24 ROM it used to interupt the GPRS session for a phone call. ANyone else that can confirm that this is just an issue in 2.24 ROM ?
Anyone else that can confirm this ?
Or maybe there is a registry setting for this ?
I have always thought it depends on what your gprs connection was doing.
if it is connected but idle, then calls will come through. if it is connected and in use, downloading a file or something, then it won't be interupted by a call.
as far as I know, this is the way gprs was desgined to work. can anyone confirm?
I dont want to go back to the 2.17 ROM just to test this. But it looks like no one out there would do it for me .... I could of sworn that it worked before..
yozh;
I have the same ROM and I DO get my calls, they DONT go to voicemail.
It's not the rom. Its the way GPRS works. Try to download constant packets of data(like streaming a high quality video) ON ANY ROM and try calling you at the same time. it can and it WILL go to voice mail.
That being said, sometimes you might be downloading a lot of data and you phone MIGHT STILL RING! This is because GPRS uses multiple different channels than then one used for voice, but this feature is just a plus, its not something you can always rely on.
Just something i wanted to add: This rom had brought me incredible reliabily on my GPRS connection and, paired with the cingular radio rom, its close to perfect for me. Maybe because with this rom the GPRS is always working full-speed and optimized, pushing the MOST of data it can, calls might be going to voicemail more often than normal? Its just a thought and maybe its a stupid one, but on my understanding the more data its pushing, the greater the chances it will go to voicemail.
Hope that helps.
Strange because MDA is class B device and class b device should
Class B
Class B mobile phones can be attached to both GPRS and GSM services, using one service at a time. Class B enables making or receiving a voice call, or sending/receiving an SMS during a GPRS connection. During voice calls or SMS, GPRS services are suspended and then resumed automatically after the call or SMS session has ended.

thats from http://www.gsmworld.com/technology/gprs/class.shtml
So thats kinda strange Im telling you Tmobile is doing something, I need someone with 2.17 or 2.21 to check this please[/quote]
Similar problem with 2.25
I just updated to 2.25 ROM and have a similar problem. In this case, it seems that once I make ANY GPRS connection, the voice channel no longer works. Outgoing call just don't connect and incoming are directed to voicemail. It still indicates a strong signal to the Cingular netowrk, and data apps still work (for example, the voicemail notifications and email keep coming in). I have to stop the data comm and then cycle the phone (voice) connection in order to get voice back.
Any suggestions? Cingular is advising me to downgrade back to 1.8 ROM - but they don't even have a link to get it!
What programs are you using?
See this thread: http://forum.xda-developers.com/viewtopic.php?t=53432
It documents the problem...
Hello Everyone,
I am having a wierd issue with my HTC Tytn.When my Data connection is active I cannot make or recieve phone calls.Any incoming call goes straight to voicemail and any number I dial the phone will display "call ended" before it even starts to to ring. The minute I close the data connection the phone works again.I have updated my ROM to the latest English ROM.Could my unit be defective?
Thanks in advance!!!
Hmmm that's weird.
Your TyTN is acting as class C device (Data or Voice), and in fact TyTN is class B device (Data is suspended while on Voice).
Is your unit defective? Possible, but... first backup your TyTN completely, then re-update full ROM, set up data connection and call to check it while on active transfer. If it will be OK - your unit is OK and this is software/registry problem, if not your unit is might be defective. This is the quickest way to determine.
My device does this as well, but only when connected to Slingmobile.
Other "always on" programs are not affecting me.
Not sure if this helps or not Just trying to add more data.
data causing call dropouts
Hi,
Hope this helps, but here in Australia when using the Telstra HSDPA network on UMTS850, when i'm connected to a data session, I can't receive calls and the caller gets the "phone is switched off" message. If I force the phone to use the old UMTS2100 network, the phone will pause the data session and allow the incoming call. On another forum I have read that this is due to a limitation in the Ericsson 850MHz hardware which the telco is using on their mobile towers and they expect an upgrade to fix it sometime in January. I don't know if this is 100% true, but it is what i have read
If I have a data session in progress it gets disconnected whilst a phone call is in progress (I can receive calls fine, although I have had one or two occasions when people have rung me and it's gone straight to voicemail without notifying me of the call). After I hang up, the data session is reestablished.
Using T-Mobile in the UK for what it's worth.
This is a very weird issue, sorry I can't offer any more info or advice.
I'm on T-mob Flext WnW and have the same issue. When I have my data connection established (either gprs or HSDPA) anyone that tries to call goes straight to voice mail. I can make a call which temporarily stops the data session and then re-establishes it after I hang up.
Is this a known issue on T-mob?
In the HTC faq, it is meantioned that the handset is a GPRS class B device:
http://www.europe.htc.com/support/faq.html?id=119
This means that the data-traffic is suspend for voice calls.
http://www.gsmworld.com/technology/gprs/class.shtml
(I haven't tested this with my HTC, but my Nokia 6260 did behave like this)
The HTC faq also states the full 3G operation ought to allow for simultaneous voice and data calls. I personally interpret this that calls are possible together with a UMTS connection (but I could be wrong).
Jörg
For all with problems with connection while on data.
Most of us here have no problem with it, might be network you are logged, not fully compatible with class B.
My advice: check different phone (TyTN) if same occures, if yes then different handset (other brands). If it still is happening - call network and demand some explanations and upgades.
Still supporting my first post to hard reset device and check if without all software you have same problem.
And for the record - most of mobile operators calls this "Ring-through problem"
JUST FYI
Cingular says that for some reaosn streaming data (for my my slingbox) will not interupt. So phone always goes to voicemail.
Once I get the higherspeed data in my area this problem should go away.
This was posted by another in response to my question, and also confirmed when I called Cingular. Although it is possible we were both misinformed by support.
I'm sure I've read about this problem in the past but I can't figure out whether there is a way around it. My model is an MDA Vario II in the UK. Is there any way to avoid missing calls when the phone is connected to the internet?
It's great having a phone with internet access, but not so great that it doesn't seem capable of functioning as a phone at the same time!
thanks
Can anyone help with this please?
thanks.
Am I really the only person with this problem, or am I just being really dumb with my forum searches?
thanks
I think there is a difference between GPRS and UMTS. When a GPRS connection is active (at least, when data is sent or received) you are not able to receive calls. When UMTS is active, calls should get through. The standard way should be that the device detects an incoming call, shuts down the GPRS connection and restarts it after the call is ended. With UMTS, the device can receive and send data and answer the call at the same time. I have actually never had any problems with unanswered calls while browsing, but I use UMTS all the time (or perhaps no-one is calling me while browsing).
I have no idea what fault in your phone could cause your problem. Try searching with better keywords perhaps in the future, I found several threads relating to this problem by using the words "data connection missed calls". Use the same words for a search and I am sure you'll find lots of threads about this.
This will always happen with any handset. if you are sat there reading a page and not loading any data then the call will interupt the GPRS connection then reconnect once the call has finished. If you are sending or receiving data then the person will get a busy tone. Sorry this is just how all the UK networks work.
Hi all,
I have a HTC Touch HD, running WM6.5, all seems fine, but every now and then I cannot dial out, either by selecting a contact or by manual dialling.
If I reset the device it then allows me to dial again, but after a couple of hours use it stops dialling out, very weird, I hope it is something that can be rectified easily?
Can someone help me with this annoying problem please?
Apart from that the rom upgrade is mega, although I also am having a problem getting O2 mms settings to work, that I can live without.
Cheers Mark
I'm having the same problem, seems your service provider doesn't support GPRS connection while voice dialing, what you have to do is: go to settings>connections>connections> advance then select network set the connection to My Work network or anything other than the operators' connection .
This is what happened to me in UAE and after spending hours with Service provider and HTC customer support, that was the only solution.
It occurs more under wm6.5 since the os connects automatically to 3g,Edge or hspda so upon resetting, the system disconnect connection and that's why you are able to call again.
I wish someone can help us developing a patch that can disable internet automatically on dialling and reconnect upon call end.
Idid that, but then could not connect to the internet, so I put it back as it was.
I noticed that the 3G setting was on, I turned this off, mainly because we are not in a 3G area, I will see what that does, many thanks for the advice.
