Hi Oliver,
The problem is in your configuration :-). cpl-c module param "proxy_route" doesn't refer to a route that does proxy(relying) as you configure, but to a route to be processed before cpl-c does proxy (this is does internally). So. basically you were trying to do twice transaction creations and req. relaying.
so, in your case, please remove the "proxy_route" param.

Hi Bogdan,
please find attached my ser configuration. I'm using the cvs head version downloaded two days ago (22.06.04). Should be actual enough ;) Thanks a lot.

Hi Oliver,
please send me your ser.cfg - it will help me to trace the problem. Also be sure you are using the latest cvs head version - there were some updates 1 or 2 weeks ago.

Hi Bogdan,
I solved the problem with SER startup. The reason was that I download the CVS head onto my notebook and copy it via ftp to the linux server. After downloading CVS head directly onto the linux server, compiling and installing it SER starts up without any error message.
But I have still the problem with call forwarding on busy or no answer. Inserting log information into my CPL script I can reproduce that SER is never processing the <busy> or <noanswer> tag and the following tags. I try out the example script from the current IETF CPL draft for Call Forward Busy/No Answer in the following scenario:
6131 forwards calls to 613 if busy -> 6131 has an active session with 614 -> 612 calls 6131 -> 6131 is busy and SER should invite 613
After uploading the CPL script for 6131 the caller 614 cannot reach 6131 and the syslog represents the attached error message.
Can you identify any mistake I've done in my configuration? Many thanks.
Best Regards,
Oliver
