Hello,
I'm installing Cisco Presence 10 on a Vmware ESXi. I have already installed a CUCM 10.X and now attempting to link these in the installation.
I have already prepared some configuration on the CUCM, i've added the presence as a server in CUCM, and also made a SIP trunk.
The SIP trunk is in service, i can also ping the installing Presence server from the CUCM
I went into the service parameters and enabled the "allow subscription" and also pointed towards the SIP trunk. The problem i am receiving is the following error message during installation of the presence:
*Configuration validation with cucm (ip address) failed. Could not send/receive UDP packets to publisher on port 8500.
- Is this node in the application server list on the cisco unified manager ( No it isn't but i can't add it, there no selection menu for it)
- Is the network connection up (Yes)
- Is the MTU Size correct for this network (Yes)
- Does the network allow packet fragments (Yes)
Anyone have an idea what might be causing this issue, there's no clear guide i've found to get this working.
