[Freeswitch-users] Speex codec in low bandwidth mode (narrowband, mode = 8, quality = 1, bit-rate = 3.95 kbps)

[Dmitriy Shumaev]

 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>
