Setting codec in SIP client
Is it possible to set the codec used in the N900 SIP VoIP client?
|
Re: Setting codec in SIP client
Examples for codecs that you want to set, please?

Re: Setting codec in SIP client
I am not sure which codecs are available, but g729, gsm or ilbc, as these provide better performance over HSPA.

Moreover, although I can initiate and receive calls, there is a problem with the outbound voice when I'm using my VoIP provider (normal telephone calls work just fine - it's not a dead mic). |
Re: Setting codec in SIP client
i can't see any way to change codecs as well, i hope this doesn't mean it defaults to g711 as it would be bad idea for 3g or even on wifi if user got slow upload speed.
for E series there is sip tool on nokia website that let us adjust this so i hope there is a way to change codecs and codecs priority on n900 :( is quite odd that such simple feature yet so much needed one is missing |
Re: Setting codec in SIP client
I agree!
I was searching for the codec too, but no hit jet. Would be great if you could tie a codec priority list to the Internet connection used (Wifi, 3G, 2,5G, 2G) or autodetection based on currently available bandwidth. Cheers Bjoern |
Re: Setting codec in SIP client
I suspect by the poor quality of outbound sound on HSPA that it is either defaulting to ulaw (g711) or has the priority set as ulaw first.
I will try to do some more testing tomorrow to see what I can work out. There is another issue with the VoIP system I noticed: If you have more than SIP account registered and you select a name from the contact list it offers "phone" or "sip audio" numbers, but it does not tell you which sip account it is going to use. |

allow=g729 or allow=gsm This might let us know which codecs are installed. |
