We seem to have a very strange issue with our CP925 Conference phone. It seems that we can only have 2 connected at any one time.
This morning the Boardroom was connected then it went offline and another meeting room came online, then after lunch, this meeting room went offline and another one came online.
When I check the phone's web page the accounts were showing as registration failed but previously they where showing a registered.
I have checked and ALG is not enabled on our firewall.
