mind I should try using auto_outcall_prefix? I tried setting
codec_string=silk@24000 and absolute_codec_string=silk@24000, but
still FS offers only SILK/8000 to the b-leg.<br>

<div>Hi everyone,</div>
<div>I got a strange problem with mod_conference and
auto_outcall taking the </div>
<div>wrong codec for b-leg. For what I can see from the
log everything seems </div>
<div>fine. The a-leg calls with the following SDP:</div>
<div><br>
</div>

<div>And the SILK/24000 codec is accepted according to the
