Bristuffed bristuff-0.3.0-PRE-1s.tar.gz no SIP Calls

I just installed the newest bristuffed Asteriksk. During compilation everything went fine. IAX Phones work fine but SIP Clients can not establish any call. SIP Client can be registered correctly!

I can only start asterisk when chan_sip.so is disabled in modules.conf. Anybody a quick Idea?

any idea ? yep, you got something wrong.

post a log file fragment and your sip.conf here if you want more specific help.
