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@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.

Hi,

 Since we installed last version of Kamailio (3.1.4)

the last version is now 3.1.5, but this is not really the most important aspect. However, it is recommended to upgrade, there were some fixed to registration handling when register requests have multiple contacts.
we have been experiencing a big problem with REGISTER retransmissions. When the server receives a retransmitted REGISTER it removes the binding and the UAC remains unregistered until next refreshing period. I include a PCAP capture that shows this behaviour.

I am not 100% sure that this problem never happened with older versions.

Has anybody experienced the same problem?
I will try to reproduce and investigate myself. Anyhow, meanwhile maybe you can provide more hints faster. Do you have error messages in the syslog? Can you run with debug=4 in config file and send the output in syslog for such a case?

Cheers,
Daniel
