SIP Registration Expiry

[IPOLackey]

Hi Guys,

Having an issue with call disconnects on a SIP Trunk. Checking into it I saw an odd thing happen. Trunk is setup to a 120 expiration, and the Registrations are going off with a 120 expiry, but the registration is coming back as 680...

I've obviously raised this with IPVS but wondered if anyone has seen this before.
