No audio after transfer
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, John From: John Rutherford Sent: Monday, December 08, 2008 4:36 PM To: freeswitch-users@lists.freeswitch.org 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
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. On Wed, Dec 10, 2008 at 8:36 AM, John Rutherford <john@loopfx.com> wrote:

So, I can hear the person that I just transferred to, but they can't hear me. Anyone have any other ideas?

MSS starts sending RTP to FS before FS is ready to accept.... so the OS catches the port not open and returns an ICMP 3:3 back to the MSS.... which in turn chokes on the queued up RTP and refuses to send anymore... -Ray John Rutherford wrote: I just emailed it to him.

We find that some equipment (in fact a lot of equipment) have features that cause issues to be quite non-obvious, so perhaps you could give the pcap to Brian for him to review. He's a total ace when it comes to bug hunting. -MC From: freeswitch-users-bounces@lists.freeswitch.org [mailto:freeswitch-users-bounces@lists.freeswitch.org] On Behalf Of Brian West Sent: Wednesday, December 10, 2008 12:59 PM To: freeswitch-users@lists.freeswitch.org Subject: Re: [Freeswitch-users] No audio after transfer would be most helpful to capture a pcap of the entire thing by itself start to finish. /b On Dec 10, 2008, at 11:51 AM, John Rutherford wrote: 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. _______________________________________________ Freeswitch-users mailing list Freeswitch-users@lists.freeswitch.org http://lists.freeswitch.org/mailman/listinfo/freeswitch-users UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users http://www.freeswitch.org _______________________________________________ Freeswitch-users mailing list Freeswitch-users@lists.freeswitch.org http://lists.freeswitch.org/mailman/listinfo/freeswitch-users UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users http://www.freeswitch.org _______________________________________________ Freeswitch-users mailing list Freeswitch-users@lists.freeswitch.org http://lists.freeswitch.org/mailman/listinfo/freeswitch-users UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users http://www.freeswitch.org _______________________________________________ Freeswitch-users mailing list Freeswitch-users@lists.freeswitch.org http://lists.freeswitch.org/mailman/listinfo/freeswitch-users UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users http://www.freeswitch.org _______________________________________________ Freeswitch-users mailing list Freeswitch-users@lists.freeswitch.org http://lists.freeswitch.org/mailman/listinfo/freeswitch-users UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users http://www.freeswitch.org _______________________________________________ Freeswitch-users mailing list Freeswitch-users@lists.freeswitch.org http://lists.freeswitch.org/mailman/listinfo/freeswitch-users UNSUBSCRIBE:http://lists.freeswitch.org/mailman/options/freeswitch-users http://www.freeswitch.org
