This trace would seem to indicate a sipxbridge/ITSP issue. Everything up until the transfer looks fine. The phone sends sipx a refer. Sipxbridge in turn sends your ITSP another invite. The ITSP immediately sends back a "500 server error". And at that point the call is torn down. I'm not exactly sure what the itsp doesn't like. The invite looks ok from what I can. The only that seems odd is that I would have though sipxbridge would have sent a re-invite rather than a second invite. But a second invite rather than a re-invite maybe acceptable. Does anybody else know if a second invite would be normal here? Do you have another ITSP you can do a test with? -M _______________________________________________ sipx-users mailing list [email protected] List Archive: http://list.sipfoundry.org/archive/sipx-users/
