[Users] Problem with Call Forwarding

Hey All, I have tried to set up forwarding using a document for SER which I found at http://siprouter.onsip.org/doc/gettingstarted/ch10.html. In trying to get it to work though I am having a couple of issues: 1) Call forward immediate and not available works, but the billing party is set to the caller and it needs to be rewritten to be the account doing the forward. 2) Call forward busy and no answer don't work at all. The caller's phone drops the call and the forwarding destination phone does not ring at all. I believe the solution to both of those problems is the same: find out how branching works and set it up properly, but I am struggling to find some documentation to help. Does anyone have a sample config they can send me. I'm sure it would help enormously! I'm using OpenSER 1.1.0 with mediaproxy 1.7.2 on debian sarge. Regards Darryl
