No. I realize that’s it’s a B2BUA and that’s exactly what we want. 

Everything with the transfer seems to work fine, except that there is no audio.

Are you expecting every message that MSS sends FS to be in turn sent to televantage?
That is a proxy behaviour.  Since FreeSWITCH plays the role of a b2bua it will not pass the
messages across a bridge.

Sorry to repost, but I haven't heard anything back on this in a little while.

I checked out the trunk last week.  I'm on revision 10597. 

Thanks,

Subject: No audio after transfer

I'm trying to get an attended transfer work with freeSWITCH, but it's not quite working.  I have Microsoft Speech Server on one side and Televantage on the other. 

MSS is originating a call, which freeSWITCH is bridging to Televantage.  That calls connects just fine.  Then, MSS sends a re-INVITE to Televantage to put the call on hold.  This works too.  Then, MSS originates another call to freeSWITCH, which is again bridged to Televantage.  This works fine too. 

Then, MSS sends a REFER to freeSWITCH to do the transfer.  The transfer should be complete, but there is no audio between the two calls—just silence.  I have looked at pcaps and the freeSWITCH logs, but I'm not seeing anything obviously wrong. 

After the REFER, I can see audio for both calls going between freeSWITCH and Televantage, so it seems that the only thing missing is freeSWITCH routing the audio from one call to the other call and vice-versa.

Any help would be greatly appreciated.  I have a pcap and the freeSWITCH logs, and I can easily reproduce this. 

Thanks!

John
