[Freeswitch-users] ILBC takes precedence regardless of the codec prefs

[Emrah]

Hi all,

I am using FreeSWITCH Version 1.2.5.3+git~20121206T050429Z~91eef34d5c (git 91eef34 2012-12-06 05:04:29Z).
When mod_ilbc is loaded, ILBC is used in any session where the client offers it, regardless of my codec preferences. This gets even stranger when you look at the SIP trace… FS doesn't offer ILBC. This is brand new, I wanted to enable ILBC just in case, and found out that I prefer it to G729.

Here's some output of a trace:

Your input is greatly appreciated, as always.
