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.
Can someone help me?
