Hi all,
Im trying to set up conditional call forwarding using an openser.cfg
created with sip:wizard on sipwise.com.
On ring-timeout before response 408 I receive a "500 I'm terribly sorry..."
message.
ngrep output:
----------------------------------------------------------------------

--------------------------------------------------------------------------
How can I solve this problem?
Attached the routing section of openser.cfg (full file was too big for
mailing list).
Thanks in advance. Best regards.
