I have CUPS 7.0 installed. When a user is using CUPC from a laptop on the voice network, presence status works well and softphone status is ok. When I test with a user from another subnet other than voice, the Presence status does not function correctly and the user status is always offline.
So from a device on the same subnet as the presence sever, I can see the user on another subnet become available and then offline, and it continues like this.
There is no firewall between the voice and other subnets on the network. All users are affected.
