Thanks, Nick! I was looking at COR settings because it is one thing that is unique to the particular call center group (they are the only group that uses this COR). It is the only group in our hospital that is experiencing this issue. We recently changed all the phones to SIP, but it has yet to make a huge difference. After all the measures we've taken to manage the issue, we agreed to involve our network team. Still, I am taking every measure possible with our Telecom team before involving the network team.

I highly doubt that the COR setting would cause the phones to go out of service. Blocking incoming calls to contact centers is a pretty regular thing and used by /many/ organizations, and what you mentioned isn't something that is common.
More likely what is happening is that there is a network disruption happening somewhere between your phones and your PROCR/CLANs. I'm assuming these are H.323 phones, and they are /super/ sensitive to network drops -- even if its for a few seconds. They depend on an open TCP socket to your server to stay up -- and if it gets closed for any reason (again, network issue, firewall, etc), you would experience what you are talking about.

Hello,
We have an ongoing problem where agent phones for a particular contact center group regularly put themselves out of service (and become unresponsive to pressing keys or buttons). The users cannot utilize their workstations (I know there is a separate forum/community for Contact Center questions, but I feel this is not germane to Contact Center discussion).
The group manager requested that we block direct calls to the extensions used in her call center. We accomplished this by setting up a COR that restricts calls to extensions that use the COR.
We have tried countless measures to remedy the issue - nevertheless, it persists. Often a busyout/release of the workstation resolves the issue for the moment, but we have yet to come up with a long-term solution.
I suspect there is a conflict between the restrictive COR and the issue with phones being put out of service, as I have been told that the problem often occurs when agents try to transfer calls.
Can anyone confirm or deny the existence of such a problem? Is there anything in this COR that might trigger the issue described above? I am posting screenshots of the COR configuration below for reference:
Thank you for any insights you can provide!
