Hi all,
I have two sipx systems connected via sipxbridge. All looks to work ok, but. When a user calls from sipx1 to sipx2 and sipx2 user tries to make blind transfer to another sipx1 user it does not work. My analysis is as following: sipxbridge2 converts Refer into Invite, and sends it to sipxbridge1. But there is "sipx1 user" in the From header. Thus the Invite is challenged, and transfer is failed because sipxbridge2 does not know how to handle that "Status 407". And this is intended behavior, as far as I understand. My problem actually happens in a bit more complicated scenario: Two sipx systems: sipx1 and sipx2 interconnected via sipxbridge and with common link to pstn on sipx1. Sipx1 user calls sipx2 user, which has personal AA with forwarding to his mobile number. So.sipx2 user personal AA makes blind transfer (Refer) to mobile number. And this Refer is converted into invite and sent back to sipx1 by sipxbridge2. And sipxbridge2 drops the challenged call. I think that there are other "challenge fail scenarios" when two sipx system are interconnected via sipxbridge. Thus using sipxbridge in distributed corporate system is not quite good. Can anybody please advise what could be done with the problem? Thanks in advance, Nikolay. P.S. Snapshot or trace is too large for the email list, but I'm ready to provide trace or snapshot if needed.
