[Freeswitch-users] codec configuration ignored by freeswitch

[Giuseppe Cardone]

Hello,

I have tried to configure a limited set of two codecs for outbound calls.
I first tried with the parameters described in the documentation in a sip_profile and then in a dialplan and then in vars.xml.

However, each time the set of codecs seems to be overwritten and the original list offered by the calling UA is applied.

I am new to FS and suspect I am missing something quite simple, can anyone lend a hand in suggesting what would cause the
described behaviour ?

Here is the essential part of the log showing the absolute_codec_string first applied:
