My System:
CentOS 6.2 (2.6.32-220.13.1.el6.x86_64)
Asterisk 1.8.11.1
FreePBX 2.10.0.4
FOP2 2.26
I recently upgraded Asterisk from 1.8.7.0 to 1.8.11.1 on my system. Mostly things seem fine after the upgrade, although I have noticed one “niggle”; on the homepage of my SIP trunk provider (sipgate.co.uk) my system now permanently shows as ‘offline’ even though it is otherwise registered fine. Calls however appear to be fine and there are no audio issues or dropouts.
I’ve been in touch with the tech’s from SIpgate and have shared SIP-debug logs with them. They think it has something to do with the fact that Asterisk is sending “Expires: 0” as part of the registration. See debug snippet at end of post.
As far as I’m aware nothing changed in FBPX between Asterisk upgrades, and the SIP registration settings are set as:
Registrations: 20 (registertimeout) 0 (registerattempts)
Registration Times: 60 (minexpiry) 3600 (maxexpiry) 120 (defaultexpiry)
I changed the defaultexpiry to 600 today (as the sipgate guys reckon that is what they need), and did an an [strong]amportal restart[/strong] but that has not helped. The SIP-debug output still shows “Expires: 0” in the registration attempts Asterisk is sending to sipgate. Weird!!!
So my question is why is Asterisk sending a “0” when it should be sending 120 (or 600 as it is now)? Has anyone seen this sort of behaviour before or know how to correct it?
I found an interesting thread on the Digium forum that suggests there is an “~expiry” option that can be appended to register statements, but if it was working before without this then can’t see why I should have to add it in now…
Thoughts??
