Hello,
I'm trying to create an audio conference between 3 IP-telephones using pjsips conference bridge. The codec I use is PCMU.
Right now the application fails when calling
pjmedia_conf_create(gServerVal.memPool,
DEF_MAX_PEERS_PER_CONF + 1,
8000,
1,
160,
16,
0,
conferenceObject);
Output:
15:27:36.620 pa_dev.c PortAudio sound library initialized, status=0
15:27:36.620 pa_dev.c PortAudio host api count=2
15:27:36.620 pa_dev.c Sound device count=9

The call returns "Error Code: 469996 - Invalid sample rate". When I set the sample rate to 44100, the sample rate seems to be accepted, although it still fails returning the error "Error Code: 220162 - Media ports have incompatible samples per frame (PJMEDIA_ENCSAMPLESPFRAME)". This is strange as I haven't connected any media port to the conference object at this time.
Am I doing something completely wrong here? Is there a default approach on how to connect more than 2 IP-telephones with pjsip? I couldn't find anything like this in the examples directory.
Regards
