Registration Issue

Maybe the programmers can check into this matter:

 

We've been running V4 for almost 2 weeks and there seems to be an issue with the registration of SIP providers. While the trunk is showing 200 Ok there is no registration on the provider's side. A restart solves the problem, but the registration may get lost again after 2-3 hours.

 

This goes for two V4 systems in two different locations with different hardware.

 

We moved both systems back to V3 today by exchanging the pbxctrl.exe (no new setup), and the registration problems are gone.

When PBX sends REGISTER message, it proposes an expiry time ("expires" header) with default 3600 seconds. If the trunk provider sends back a different value, it is PBX's responsibility to re-register before that time. So, we can take a look at the registration log & see who is the culprit here. Other option is to change the proposed duration on the trunk to a lower value.

Stability depends largely on the usage of a session border controller by the service provider. For example, if there is no SBC, you must have a routable ("public") IP address, otherwise you will always suffer from instable registrations. IPv6 will solve the problem.

I have tried changing the Keep alive down to 20 to see if that helps. But we are having this problem 2 VoIP providers. Callcentric and Clarity. With callcentric I loose inbound calls. Outbound will continue to work. With Clarity this issue is a little different. The calls are not clearing off thier trunks. It is like they never get the bye message. Btw Steve and the folks at Clarity are GREAT to work with. Any help would be greatly appreciated. I have wireshark captures already.

We would like to see the wireshark for the Clarity case. Please send email to support@pbxnsip.com. It is interesting to see if the PBX sees BYE.
