FreeSWITCH Version 1.2.6+git~20130104T154559Z~a4247651ca (git a424765 2013-01-04 15:45:59Z). I'm trying to use speex codec in mode = 8 (quality = 1, bit-rate = 3.95 kbps), but it seems that it only works with 24.6, 42.2, 44.0 kbps (quality = 10). Can FS work with other modes/quality (I'm only interested in mode = 8)? If so, what should I do to configure it to use specific mode / quality (i.e. 8 / 1)? I've modified file <speex.conf.xml> as follows: <configuration name="speex.conf" description="Speex codec configuration"> <settings name="default"> <param name="quality" value="1"/> <!-- !!! --> <param name="complexity" value="10"/> <!-- !!! --> <param name="enhancement" value="false"/> <param name="vad" value="false"/> <param name="vbr" value="false"/> <param name="vbr-quality" value="4.0"/> <param name="abr" value="0"/> <param name="dtx" value="false"/> ... </settings> </configuration>
