Hi,

very happy with freeswitch as a PBX/softswitch/SBC system its working solidly for a few weeks now  - just great


I have a question regarding ringback tones - custom or regular  - I cant get freeswitch to send ringback using G729

I used the following settings ( it will just play one of the IVR prompts as ringback (filename  ivr-to_repeat_these_options)  - I took it from the G729 encoded files package , it has PCMA , G729 G723 extensions )

 <extension name="inbound_routing">
            <condition field="destination_number" expression="^4420885767(0\d)$">
                <action application="set" data="ringback=/usr/local/freeswitch/sounds/en/us/callie/raw_files/ivr/ivr-to_repeat_these_options"/>
                <action application="set" data="instant_ringback=true"/>
                <action application="bridge" data="user/10$1"/>
            </condition>
 </extension>

when I call with  G711 enabled , it plays the file no problems - see log

mod_native_file  works well for me when used in applications and plays G729 files no problem

any ideas why is that happening , any suggestions on how to resolve ?

thanks
