We have IM&P pub and sub on 9.1.1-41900 and we have just moved the machines from physical hardware to a virtual environment.
Everything went fine apart from one issue. When the users are assigned to the primary node the "on a call" presence status does not work. When we move the user to the seconday server it works fine.
After a thourogh analysis I see that the sip publish leaves the CUCM to the primary node (sip proxy) and then sip proxy server tries to send it to the presence engine on port 5070 on the same server (primary presence) but it cannot establish tcp connection. It turns out we cannot telnet on port 5070 on that server but we can on the secondary (that's why the presence "on a call" works when the user is assigned to the secodary)
The server does not listen on that port even after a full server restart, or even a service restart. The service appears is running on both gui and cli. The service also listens to port 6603 and all other ports on 66XX range which means that it has connection to the presence datastore.

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
