[SR-Users] Problems with Mar portion of registration [IMS]

[Daniel-Constantin Mierla]

Hello,

I haven't played with IMS modules, but you said is causing scscf to die 
-- is that a kamailio instance? What means 'to die' -- does it crash? If 
yes, can you get the syslog messages and the gdb backtrace?

Cheers,
Daniel
