[SR-Users] Problem with REGISTER retransmissions

[Alejandro Mingo]

Hi Daniel,

I've just installed version 3.1.5 and the problem still occurs. The 
output of the command "save (location)" is 1.

I send you PCAP traces, the kamailio log and the "kamctl ul show" log 
second by second. The AOR is "phoenixMaster at sip.aeq.es". The CSeq of the 
retransmitted REGISTER is 27871 occurring at 10:09:43

This is an important issue for us. Thanks again.

Alejandro.
