No Presence lnformation After Login Problem

You receive no Presence information after login. Solution

Complete these steps in order to resolve this issue:

Make sure that the DNS server the PC is pointed to can resolve the fully qualified name of the CUPS server.

The host entry will not suffice, you must resolve via DNS.

Check the SUBSCRlBE CSS on the SlP trunk to CUP.

This CSS must include the partitions of the devices you are trying to receive status on.

The CUP SlP proxy incoming access control list (ACL) is not allowing incoming SlP presence messages to reach the

presence engine. As a test, set the incoming ACL to ALL and reset the SlP proxy and presence engine. Log in again to

the CUPC and try to reconfigure the incoming ACL properly.
