[OpenSIPS-Users] SIPv6 UA Can't receive a 500 (Server Internal Error) response from openser-1.3.4-12.fc13.i686 register server when sending a REGISTER with the equal CSeq header field value to the last value of CSeq or lower than the number

In the trace you sent I see an increasing Cseq val ( 1 in the first 
REGISTER and 2 in the second one) and not the case you reported ( equal 
or lower than the last used)......?!

Regards,
Bogdan
