[SIPForum-discussion] spixtapi library

[Rathan Raj]

Hi, 
 
I am using sipxtapi libraries. If anyone has used the same for developing a
windows based UA, please inform me on the following issue:

I tried using:
- sipxConfigSetAudioCodecPreferences
- sipxConfigSetAudioCodecByName
and tried to set the codec to 
- AUDIO_CODEC_BW_LOW
- iLBC
respectively.

Both the fnc calls return SUCCESS but the call switches to normal PCMU
stream after a while.

Can you please let me know how to use lower bit rate codecs such as iLBC,
GSM and G729?

I have added the sipXtapi.lib and sipXtapid.lib files to my VC++ project and
am using the two header files: 
sipXtapi.h
sipXtapiEvents.h

Is there anything else I need to do? 
I call:
- sipxConfigSetAudioCodecPreferences OR
- sipxConfigSetAudioCodecByName

before:
sipxCallConnect, sipxCallAccept



Thanks & Regards

 

Rathan Raj
