[OpenSIPS-Users] Registration questions

[Bogdan-Andrei Iancu]

Hello Cinthia,

But when your phone re-registers after reboot, at the SIP level:
    1) what is the reply code to the REGISTER ? is it 200 OK ?
    2) if 200 OK, what is the Contact hdr in the reply ?

Regards,
Bogdan

The phone sent a new REGISTER with a different call-id.  There's no new registration created as far as I can tell, because otherwise I would expect to see two entries, one new and one expiring, instead of just one listing.  The old call-id showed up when I use "opensipsctl ul show".

If I do "opensipsctl ul show", I see those registrations that are supposed to be gone are still in the result, with Expires = "deleted" or "expired" for the next 10+ seconds.

A power blip knocked it out for a short while.  The registration in OpenSIPS becomes "expired".  The device is now back online and tries to register with a new call-id before the old reg disappears from OpenSIPS.  What I'm seeing is that the current registration still has the old call-id.  It is causing issues when we use the callid option of registered().
