I've just tested the same configuration under asterisk 11 with chan_motif/xmpp. Everything works great. DTMF codes get thru to IVR behind a Google Voice entrance. This means, that either FS dingaling driver doesn't work correctly or there is a mess in dtmf signaling between dingaling and sofia.

Hi, does anybody know how to pass dtmf codes to an IVR behind the Google
Voice entrance number?
A simple example code from http://wiki.freeswitch.org/wiki/Google_Voice

<extension name="google_in" continue="true">
<condition field="caller_id_name" expression="^(Google Voice)$" >
<action application="log" data="Google Voice Call Incoming" />
<action application="set" data="execute_on_answer=send_dtmf 1"/>
</condition>
</extension>

doesn't work for me. DTMF codes can't get thru. Everything else other then
that works fine.

Any help would be very much appreciated, Dmitry
