Joan,<div><br></div><div>The screenshot is suggestive but it tells very little about your issue.

we upgrade the server from 2.5 to 2.6 two weeks ago. We've notes problems with the registration after upgrade, specially with one ATA model. After many tests, I think the problem is that after registration expiration (configured to 3600 seconds in the ATA) is very dificult for that phone to re-register. It fails the registration process many times. Before the upgrade there were no problems.<br>
As you can see in the registered users graph attached, there is a very important difference before and after registration. We have changed the NAT managing of the system (first managed by routers, now by sip server) and the problem still remains.<br>
Let me know if you have any ideas about that<br>
The ATA model is Cisco SPA112<br>
