Hello,
10x for the info.
Vadim, I think this function should be included in phApi.h, don't you
think?
Yes,
but i would call it phGetCallCodecs and it should return both (audio and
video) codecs
Does this function handle the actual negotiation:
ph_call_retrieve_payloads(phcall_t *ca, eXosip_event_t *je, int flags) ?
How does the negotiation work?
The first codec that is available for both parties is taken? Does the
order in which codecs are added really matter?
Yes the first codec available for both parties is chosen which impiles
that the order DOES matter

Hello,
1. Call must be dropped. Error code maybe 488.
2. phCall structure have a audio_payload_name attribute. I do guess
something like this in phapi:
MY_DLLEXPORT int getCallAudioCodec(int cid, char* codec, int
codeclen)
{
phcall_t *ca = ph_locate_call_by_cid(cid);
if (!ca)
return -PH_BADCID;
strncpy(codec,ca->audio_payload_name,codeclen);
return 0;
}
3. Dunno :)
