Thanks a lot. It seems that the log line

5(391) authorize(): Invalid nonce value received, very suspicious !

is the key -- Jan will probably handle that better than myself.

Are you sure you applied the solaris/digest patch? (See nonce validation in ISSUES on SER's website. See also the topmost solaris-specific issue -- better take SER sources and recompile them without DBG_QM_MALLOC in Makefile.defs)

If things don't work then, send me please captured SIP messages too. (Use tools like "ngrep port 5060" to record them.)

Thanks,
