[OpenSER-Users] Bug or bad config?

Hi all, I’m 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: ---------------------------------------------------------------------- U proxyip:5060 -> clientip:1025 SIP/2.0 500 I'm terribly sorry, server error occurred (1/SL).
