IP Office 500 SIP trunk re-registration 1

[technicaluser4]

Hi,

I have registered with a SIP provider and everything works well until after 10 hours or so the IPO stops registering with the provider.

When this happens the IPO does not try any more to register with the provider however outgoing calls can be placed. The provider told me that they can see that the reigistration stops and that outbound calls can be made without registration.

Does anyone knows which of the paramters shall I fine tune so that the IPO?
Registration is ticked on and RE-INVITE is ticked off.

Thanks.

This was an issue on 4.0/4.1 on Lan2. either upgrade or use LAN1. In some cases if you set the sip lan port to NONE rather than Lan1 or 2 it also fixed.

I am using 4.2(17) but I will try this out.
Thanks.

I also noticed this only happened on a few providers, who are you using?

The provider is voiceworks in the Netherlands

There is a special build for this issue, created per my request. The build nr is 4.2(172202). We had the same problem with Voiceworks (and Asterisk).

It's kind of a long story but the bottom line is a 'bug' in the sip messaging, specifically Cseq numbers which should be incremented in sequential register messages but are not. This build fixed that issue. Permanent fix will come in next quarterly build.

Ask your distributor for it!
