CUPC 7.0 losing presence status (behind firewall) TCP ports usage
I've CUPC 7.0.2 with CUPS 7.0.6.
There is a firewall between the user's workstations and the CUPS.
I opened the networks ports detailed in the CUPC release notes.
I use CUPC as deskphone control mode
When I start my CUPC, everything is working fine.
However, after some times, I lose the presence status of my contacts, they can't see my status neither. When I change my status manually, the change is not done on the client itself. I can't see anything special in the logs. All other features are working fine (CTI-LDAP-IMAP)
When the problem occurs, I can see dropped packets in the firewall. The packets are TCP, source ports 1xxx, destination ports 3xxxx-4xxxx. The packets are sent from my CUPC to the CUPS. I don't know what are these packets for. I can't find them in any release notes.
I have to restart my CUPC to solve the problem. Also, when I allow all in the firewall rule, I don't have the problem.
I had CUPC 1.2 with CUPS 6.0, without this problem. SInce I upgraded to CUPS 7.0.4, it's there.

Check the Read Me notes on CUPS 7.x. There are new requirements to have the ASA upgraded to 8.3 I think... I cant recall the exact number. The ASA is doing a sip inspection most likely and messing up the presence packets.

The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
