[Spce-user] mr3.4.1 sems: "no matching Contact - deregistered" / kamailio-lb contact (un)masking

Sun Aug 24 05:05:41 EDT 2014

Hi all,

I have a fresh install of mr3.4.1 (actually I messed up upgrading from 
3.3.1 on a mysql error and didn't have a proper backup; my bad. 
Completey wiped the VM and started from scratch).
SEMS is successfully registering with my SIP trunk provider, I can call 
to and be called from the PSTN.
However, looking at the sems logs ("debug: 'yes'" in config.yml, 
attached), it is re-registering every 10 seconds because of a "no 
matching Contact - deregistered" error.

Below is the output of ngrep-sip for one attempt. I'm no expert but it 
looks like the unmasking of the contact fails in kamailio-lb.
178.X.Y.Z = public IP address
12345 = didlogic user id

I'd appreciate any help.

Thanks,
Arjan
