Hi,<br><br>I am having trouble getting my configuration  right so that I can have a call transcoded to Speex wideband from another codec (alaw or g.722).<br><br>If both phones use Speex wideband with no transcoding required by FS, the call succeeds though.<br>
<br>My codecs are listed in vars.xml as follows:<br> &lt;X-PRE-PROCESS cmd=&quot;set&quot; data=&quot;global_codec_prefs=speex@32000@20i,speex@16000h@20i,G722,G7221@32000h,G7221@16000h,PCMA,PCMU,GSM&quot;/&gt;<br><br>&lt;X-PRE-PROCESS cmd=&quot;set&quot; data=&quot;outbound_codec_prefs=speex@32000@20i,speex@16000h@20i,G722,G7221@32000h,G7221@16000h,PCMA,PCMU,GSM&quot;/&gt;<br>
<br>However if I make a call from a phone A using, say, g.722 to a phone using Speex wideband, the SDP in the invite from phone A to phone B does not include Speex wideband.  In fact the SDP includes speex/8000 even though speex/8000 is neither enabled in vars.xml, not in either of the phones.  Here is the codec listing in  the SDP of the INVITE from Freeswitch to phone B (from Wireshark) :<br>
