They have a problem with g722 and early media.  Either turn off g722 on the phone or actually answer the call prior to bridging.  I have a ticket open with Siemens on this with traces but have heard nothing recently from them.<div>

     I have a bit of a problem with placing outgoing calls with my<br>
Siemens on my freeswitch PBX, which seems to have to do with the way it<br>
handles sending a ring signal to someone on the call.  Instead of the<br>
method used by other PBX&#39;s, it seems to send audio back, rather than<br>
being content to let my sip device take care of sending me the ring<br>
signal.  Consequently, it has a hard time negotiating media when someone<br>
actually picks up the call.  Can I fix this?  If so, how?<br>
Thanks,<br>
Nick<br>
