[Asterisk-Users] Speex codec problems

[Branko Samardzic]

I am trying to tweak my Asterisk servers to talk to each other using Speex
codec.
I downloaded and installed speex and speex devel libraries, recompiled
asterisk (including make clean), did set up speex codec as only one allowed
on both sides. Sounds enough.
However, conversations are not Speex encoded!!! It is codec 64 (16 bit
Signed Linear PCM) all the time.
Any clue as to why Asterisk don't want to kick in Speex into play?
BTW One asterisk (initiator) is HEAD version, another is asterisk-1.0.9.

Any help is wappreciated.
