Hi all,
Thanks for the wonderful forum and contributors.
I managed to test the the VoIP Settings successfully on the HTC Smart Phone (Dopod 830 Pro). It works well with test SIP server and only 1 thing is i am forced to use G711 which produce bad quality over 3G or Wifi due to limited bandwidth. In reality, Without using compressed codec like G723, G729 or GSM, all calls will have bad quality due to bandwidth congested by G711 codec.
1. Is there a way to enable G723 or G729 codec from the WM6, in registery or somewhere ?
2. If above not possible, is there a way to enable GSM instead of G711, Seems that the call is defaulted to G711 when VoIP calling is made and there is no way to set preference on GSM. I saw some post about GSM could be bundled in WM 6.
Thanks you for your time.

Hey people.
I've been trying to listen to an internet radio station, and after about 45 seconds it says 'buffering...' followed by an error message saying it 'can't play this file', or something similar.
I can re-click on the link and play another 45 seconds before the same problem occurs.
It happens with different stations.
Any help?
thx,
b
anyone?
Update:-
the problem seems to happen when I'm on the move.
Any help?
for me .. my provider blocks audio streaming and get an error when i try to stream audio from the interent........... but in ur case if it only happens when you are on the move it could be bad handing-over between cells......
Hm, don't know if GPRS has enough bandwith to bring you that much information in time.
I guess, the GPRS downstream isn't that wide to carry all that amount of data for that stream. On cell handover or in case you are in public places (where a lot of people are using one single GSM-cell) the bandwith is reduced as well (because voice gets priority over GPRS).
Audio-Streams over GPRS - anyone who did this till yet?

there is a program for nokia 6630 that you can connect to many radio stations and stream radio in a very good quality.... my friend tested it (works in a GSM company here) and worked good for him.....
As the Nokia 6630 is a 3G Phone (UMTS,Edge), I believe it's more likely that it's possible to use audio streams with it, because 3G supports higher bandwidth.
As our little helpers are only able to use GPRS and this has it's limitations (bandwith is reduced in case of many people using one GSM cell, etc. - as I stated above), I guess the dropouts mentioned by Bennage are technically determined. The stream is - simply spoken - not delivered fast enough to the mobile, so it runs out of data, has to fill the buffer again, plays, runs out of data, and so on...
Maybe I've got time to check this here. Never thought of listening to audio streams via GPRS before (volume charged), but now it's just curiosity which incites me :wink:

another reason for the dropout when on the move could be related to switching connection as when one moves about one change from one antenna to another
this would likely cause holes in the stream

it's true that the nokia 6630 is a 3G phone but both of our service providers are running 2.5G networks.. so they are not using EDGE just plain GPRS........ and just to check i used my friends SIM and went to www.windowsmedia.com and i was able to stream with great quality and no dropouts......... so it is possible to stream audio but sometimes SP they block aduio streaming as in the case of my service provider........
hope that helps
3G == UTSM
2½G == EDGE
2G == GSM
1G == NMT
so if it's on a 2½G network then it have a much higher transfer rate then a xda2 which dont support anything but GPRS on 2G
true but edge is not enabled it here yet.....!
he said it's a matter of installing software to their servers to enable it...
Hi there
In case any one is interested I am trying to develop a voip client and switching back end that will support both GSM and G723 codecs. So far from other sources it seems that only G729 and G711 are supported and the bandwidth usage of these codecs defaets the potential for using voip over 3g due to the high xcost of data. I am hoping to be able to provide acceptable quality with GSM & G723 codecs in around 10-13kbps and 20-23kbps including all of the overheads , this compares to about 31kbps for g729 and 84kbps for g711. I Think you will see the advantages of achieving this.
If anyone else has any experience with g723 or GSM codecs on PPC please let me know.
regards
Charlie
You have a PM.
Hello all I'm with T-Mobile after getting upset w/AT&T. No matter what
player I use the video is more trouble than it's worth. I have an
unlocked 8525 which is a 3G phone, all T-Mobile has is GPRS or Edge
Networks. I've spoken to my provider & to HTC. They say without the 3G
network I cannot *have video. I know that's not true, I used to be
able to watch news feeds or whatever with a Razor. With a 500.00 PPC Icannot??? If some oneone could explain away around this problem it
would be much appreciated!
I'm running Shcap's 4.00 ROM
Radio 1.54.07.00
I know to use the search here & Wiki & any MOD here can look & see I've searched until I'm blind & confused. I guess I've read too much. I've tried 4 or 5 different radios, I'm all out of ideas. As I said any help would be much appreciated!
it all comes down to the resolution of the video
if it's 640_480 then your screen will only show ½ the pixels anyway
but it will still transfer 2times the data down
personaly i would not bother with video on grps it's
too slow even for me to surf without loosing my patience
So I guess the only fix is to drop T-Mobile & goto a 3g carrier? My contract will not be up until June & by then there should be all kinds of new PDA's out there. I guess it would be just as well for me to use a GO Phone & pay the 150.00 X-L fee & call it a day!
in TCPMP goto Options, Video, and select Raw FrameBuffer.
DirectDraw is not compatible with WM6 from what I hear.
This fixed choppy video problems I had with Youtube videos and TCPMP.

8525 (Hermes) has been notorious for crap video playback, depending on which ROM you use. The ROM the TC is using should be loaded withe the decent drivers. Best thing i use is Coreplayer and it works fine with Hardware acceleration.
Directdraw DOES work with WM6, select YV12 overlay and it should be fine.
GPRS is pretty poor bandwidth and bearing in mind it is rate adaptive so is unlikely you get anywhere close to the theoretical 80/60 kbps maximum. In a sence TMobile was correct in that 3G really is a good idea when planning on using streaming media. Depends on loads of things like the resolution, framerate, bitrate, bandwidth, codec etc...
I just wanted to say thanks to everyone for there input.Being new to all this, I need all the helI can get. I plan to flash Schap's new 4.30 full to my phone this week, I hear that TCPMP is more less the same as Coreplayer. Is this true or not? I do have one question. Which radio using T-Mobile has worked the best for everyone in the MO & AR area of the USA? I think this may have something to do with it. Thanks for the input!
Has anybody tried to make a Video Call ?
What others devices, Windows Mobile, can Athena establish a video conference?
Is there any third parts software, for the rest of Windows Mobile devices, with only one camera maybe, which is available and compatible?
I do videoconference calls with any cellular having 3G and the ability to have videoconference.
For sample my colegue at the office has a Nokia N70 and we have regular videoconference calls whenever I find a problem in a building that I want to show. So I do a videoconference and once connected I swap the videoconference to the read camera in order to show the problem to my colegue.
I try it with some other Nokia and works too. Offcourse they need to have videoconferencing capabilities. And off course you must be in a 3G network.

I have found that whichever Voip program I use, I get poor voice quality on VOIP via UMTS or EDGE, whereas my old Nokia 6124 worked way better. I then saw this post
http://forum.xda-developers.com/showpost.php?p=9579987&postcount=11945
and I wondered if there are any differences between the modems in terms of jitter, because that could be really messing up VOIP streams. My modem is now XXJP2. Has anyone tested various modems for voip reability?
Hi, I have been able to successfully use my SGS for VoIP regardless of the modem version. The program (stack) and codec you are using are more important in this respect. The main difference between Android VoIP solutions and Nokia's SIP is that on android sip drains battery like crazy unless you configure your pbx to connect an extension over TCP rather than UDP. Good luck!
