Thanks for information.
But I am not able to use any other codec than PCMU/PCMA for some reason. I read related settings and what they mean.
I am using Vitelity for now and they say they do support G722/GSM/G729 on their end.
The far-end SDP says it supports PCMU/PCMA/GSM/G729 only, no G722.
In vars.xml, I have <X-PRE-PROCESS cmd="set" data="global_codec_prefs=G722,GSM,PCMU,PCMA"/> <X-PRE-PROCESS cmd="set" data="outbound_codec_prefs=G722,GSM,PCMU,PCMA"/>
The only matching codecs are PCMA/PCMU/GSM from what you've shown us. You have some G726 comparisons in your log as well, but you've not mentioned G726 at all.
