GPRS and Phone calls

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.

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?

missing calls when listening to streaming audio

Hi. I have a T-Mobile MDA running xelecien's 2.26 rom. when I stream audio with TCPMP (core player) or windows media player, all incomming calls go straight to voicemail. every so often a call will get through, but it's very rare. has anyone else experienced this issue? any workarounds? I mainly use the siruis player ver. 1.6.1.31192 with TCPMP on the memory card. whether I leave both programs running, or run TCPMP in the background with the siruis program close, I miss calls. any suggestions? Thanks, I appreciate it.

Fairly simple really - it's how the GSM network is designed to operate. You can have either a phone call or an active GPRS or EDGE connection - you can't have both, at least not at the same time.
If you are steaming music, calls will go to your vmail - likewise if you are on a call you can't use the internet.
Hope this helps.

i read somewhere that it has to do with the network also.. Tmobile has a tendecy to put data over voice.. as cingular puts voice over data

this is very true i have t-mobile and if im using like im+ and im connected to inet i wont get all my sms and calls. its fairly irritating. kinda makes me not wanna have internet on my phone.

^I tested that yesterday with IM+, I repeatedly sent messages and tried calling myself with another phone, call went straight to voicemail, then I tried it again when I wasn't sending an IM and the call came through, so you're phone will still ring as long as you're not sending or receiving data. Yes this is stupid and I wish t-mobile would put voice over data like cingular. T-mobile has inexpensive plans, cool phones, great customer service and the ****tiest coverage of any company out there WAY TO GO T-MO!!!

thanks for the respsonse.

Incoming calls not received when online

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.

GPRS Issues

Hi
Ive had my Advantage for two days now, and i have missed 16 calls, even though the phone is on and has full signal, after playing around this afternoon it appears to be if there is a data connection active (GPRS) ie active sync live search maps, remote desktop calls get rejected.
Ive had an JasJar for the past year and never seemed to get the issue with that, and im using the same SIM / Network / Number i was before.
Does anyone have any ideas how to get the phone to pause the data connection so the phone can ring?
Does anyone else have the same issue?
Regards
Ben

you don't happens to be using Vodafone do you? If so i know exactly what is going on.....

Nope
No, i am on tmobile UK, what i don't get is that i works fine if i swap the sim back to my JasJar.
Ben

I miss calls all the time, about 70% of my calls fail for some reason or another.
T-Mobile Suck. I never had this much trouble with O2.
I have done experiments where somebody stood next to me calls me, and gets "the number you are calling is not available" while my phone, next to them is turned on with full battery and signal...
Even outgoing calls fail randomly, just says "calling" for ages then stops for no reason.

Ive had not trouble with tmobile since i have been with them (over 18 months) until i got the advantage, ive cloned every single setting i can from my jasjar and still no look, its a shame as looks like im going to have to disable push email!

that is strange, mine one now works perfectly, so when you miss your call, are you on 3.5G( HSDPA ) network or are you on GPRS?

Standard GPRS, it only happens when there is a contasnt data flow if it is just connected and the connection is not being used it calls in fine.
EG if i use remote desktop / terminal services over GPRS then call the advtange at the same time it goes to answer phone, although it does take around 10 seconds before it does though but doesn't ring, like it is looking for a signal/trying to connect.

may i ask is there any reason why you are not using 3G? GPRS tend to have this problem, but 3G won't.

Coverage, my house and my office don't have 3G coverage, else i would be.

i was on o2 b4 n hardly ever had 3g signal n when i did my video calling never worked....since moving 2 t-mobile ive had no problem....my data connection is mon 9 till 6 b it 3.5g, 3g or gprs n i use cortado.com push email service for instant emails.....i still receive calls when connected
using the flext 50 with web n walk

I'm in the US using T-Mobile and GPRS and don't have this problem. I'll try to make it "break" and see if I experience the problem but just never noticed it.

If using GPRS and a call comes at the exact time you are receiving data, your call will go to voice mail or unanswered. Its the way the radio is designed...SOme carriers have been successful at ending the data stream and raising the priority of the voice. But GPRS modem in most phones only allows data or voice not both...but,
If using 3g/utms it should ring on the phone. And allow data and voice at the same time.
Maybe you universal is grabbing the 3g signal and for some reason the 7500 is using gprs.
Wu has also reported this problem with Vodaphone and Hsdpa...

that is very correct, i have just change to T-Mobile yesterday, now my HSDPA works perfectly with voice, when voices comes in, it will switch the network to 3G and allow voices to comes in, data is still connected, just lower the bandwidth. Too bad that this doesn't work on Vodafone

Has anyone found a solution for this?

there is no solution, the only thing you can do is swap your operator, or just don't use 3g at all....

Enable calls while on EVDO

Question for you guys,
I never noticed until my girlfriend tried to call me. I was streaming videos on youtube on my touch from Telus mobility and my line was just ringing, not going to my phone. Is there anyone that knows how to enable this? I tried looking online but codes for other phones like the apache dont work.
Thanks,
e

I was trying it out on my Bell HTC touch and it works fine (was on IE browsing and called my cell and it came through)
How exactly are you viewing the YT videos? Could be the application your using.

Im using TCPMP and flash media bundle. Found it on PPCGeeks

I don't think that the CDMA Touch can handle concurrent voice & data radios.
Meaning - it is either one or the other.
If you are browsing the internet, and a call comes through, it will drop the data radio and enable voice. Your example of the browsing and a call coming through is an example of this.
Try talking on the phone and then surfing to a new site in PIE. You can't.

100% true, it can do 1 or the other not both

definetly not true...my bell htc touch works while surfing the net, it just switches from the EVDO network to the 1X, and it doesnt just keep ringing...so im not sure about sprint but the bell service allows for them to b working at the same time...
good luck

NOT TRUE AT ALL! I confirmed (as you can see in my post above) that it receives calls even if your in between a data session.
I know on regular 1x phones they are not able to do this but this is a feature of EV-DO where it allows a phone call to come in even while surfing or using data.
To the OP, are you in 1x data mode or ev-do?

K so ive been testing it, while surfing and actually going through links and receiving a call they dont go through as well as streaming. But if Im on a page and not doing anything but reading whats on the page the call comes through. And I am on Ev-DO

From what I understand, if and when Sprint/Bell/Telus upgrades the rom to support EVDO Rev.A, then you can have voice and data concurrently. I find when I am surfing, it really depends on the timing of the call on whether it rings or not. If you are actively downloading data (streaming, accessing a page), then the phone will not ring. If you are just reading/viewing a page after it has fully downloaded, then your phone will ring.

Hi Guys,
I got the Telus HTC Touch about a week ago, and I went through the same thing. I called Telus's tech support as well as HTC's, I kept getting the run around; Telus was telling me it's an HTC issue, and HTC telling me it's Telus's issue, until I finally spoke to an admin in Telus' tech dept and he told me it's a know issue that will not be fixed anytime soon.
The only time this happens is when the data connection is "active" i.e. it's downloading something, so if you are streaming, the call will never go through to the phone, it will go the voice mail and your won't get a missed call notice on the phone. If browsing the net, and IE has finished loading the page, the data connection is "idle" and the call will go through.
I have read on a forum that there is a way to fix this by accessing the Data Programming screen using ##8323# and chaging the priority to voice from the default data priority, but I was not ableto access that with my phone.
I am still hoping to find a hack for this; for now I call-forward my HTC to my Blackberry when I know I will be using the internet heavily so I won't miss any calls.

TRY ##DDTM# thats how its done on my sprint touch

Ludester - can you try this again?
I know that if you are surfing and a call comes through - you can get the call and answer it. That's what I said in my reply. That's because the phone drops the data connection and enteres the voice connection. If you jump back to PIE - then your previous cached page pops up.
But, try calling your handset from your home phone. Answer it. Leave the line open. (you may want to stand a few feet away from your landline to avoid feeback).
Now, while you have an active voice connectoin from home phone to cell phone, Open PIE and try and start browsing to a new page not cached.
Does it give you a message?
My understanding is that Rev0 doesnt do simultaneous voice and data. Actually i dont think RevA will either, although capable by technology, Sprint's implimentation wont allow it. Only way to get voice and data simultaneous right now is use HSDPA on GSM it does both at the same time currently.
I would love to have concurrent voice and data. I just don't think Rev0 has that feature and don't believ ewe will see Sprint's implementation of this feature through the RevA update either. I surely hope to be proven wrong on this - because that is indeed a desired state for me.

just yesterday i tried going to the other way... while on a call, i tried to access live search to map an address. the call was disconnected.
today i tried to launch internet explorer while on a call and i get a message to 'end the current call... blah,blah'

I'm on Bell and I was streaming music to my phone today and a call rang through no problem.

Same here on Bell.
I was streaming music on EVDO network. When I called my Touch, it started to ring. At that moment music streaming stopped and Touch switched to 1X network. When I ended this conversation, Touch switched back to EVDO and music streaming resumed automatically.
Cheers,
Romek

For voice as priority should it be enabled or disabled? Sprint Touch.

i believe that all issues with cellphone internet blocking or being disabled when one recieve a call is purely an issue
with old and poor quality equipment of the cellphone operator in the area

You have to call, on a telus touch, ##778 and you gotta have your MSL code to edit things... But I haven't found anywhere that priority you're talking about...
I thought EVDO Rev 0 (like the one Telus is using for now) cannot handle data and voice connection at the same time... It is different for EVDO Rev.A, I've seen that on wiki I think

I had this problem until I realized I had changed my settings to "Force HDR" mode which only took advantage of EVDO.
I changed it back to Automatic switching (at the expense of battery life, however) and tested it out by running Sprint TV and having another phone call and it worked.
I checked the ##DDTM# and it was already disabled.

I've had the same issues... including the girlfriend being pissed off because her calls always went to VM. The problem is related to what network you're using.
The link below explains in details what networks allow both data and voice at the same time:
