<br>
That is, then I see the SEMS registering the reply and counting down
from 200sec (see attached SEMS log).<br>
At 50% of the expires value it will reregister, as per the following
method I guess:<br>
<br>
bool AmSIPRegistration::timeToReregister(time_t now_sec) {<br>
return (((unsigned long)reg_begin+ reg_expires/2) < (unsigned
long)now_sec); <br>
}<br>
<br>
<br>
I'm still trying to get the hang of all the logic in the kamailio.cfg
routing and I have no idea of all the SIP scenarios involved, but in
general I would expect that for incoming messages to the loadbalancer
that have ngcpct set, kamailio should unmask the contact. Or is that too
simplistic?<br>
<br>

I attached the output from
"ngrep-sip didlogic" for a minute or so, showing the 10 sec interval. I
also included the sems.log for that same period.<br>
<br>
I did a grep on expire in all logfiles in /var/log/ngcp/ but there never
is an expires: 0 in the logs, only 3600. Any other idea how to find
such an unREGISTER?<br>

sorry in the trace below I just see the registration process at
09:39:43.<br>
Where do you see the second REGISTER after 10sec ? It should
Re-REGISTER again after 3600 sec.<br>
<br>
Also I don't see the unREGISTER message (with Expires: 0).<br>
Can you provide such messages ?<br>

__pbrmquotes="true" class="__pbConvBody">Hi all,
<br>
<br>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).
<br>SEMS is successfully registering with my SIP trunk provider, I can
call
to and be called from the PSTN.
<br>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.
<br>
<br>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.
<br>178.X.Y.Z = public IP address
<br>12345 = didlogic user id
<br>
<br>I'd appreciate any help.
<br>
<br>Thanks,
<br>Arjan
