Knowledge sharing, I just deployed CUAC Advanced 12.0 “Pub and Sub” with CUCM 11.5 I used Cisco CUAC Admin guide for configuration in CUAC and CUCM, after all servers is up and running I stuck with issue that I have more than 1500 CTI ports to sync between CUAC and CUCM, once I start sync it was working fine with around first 350 Ports it’s shown as registered in CUCM, but once I exceed this number all other ports start to be in unregistered and none status in CUCM, I try all the troubleshooting documents in Google but it’s not working, I check the logs in CUCM and CUAC, what I found in CUAC logs that “Error cannot reserve media” include the name of CTI ports that in None OR unregistered status, I try to uninstall TAPE and Install it again but I don’t guess this is related because some ports already registered and I restarted CTI Manager service in all nodes.
So after 3 days stuck in this issue, I uninstall TAPE from CUAC Pub and Sub, and download TAPE from CUCM, in the installation process for TAPE in CUAC I notice that there is Media driver allocate UDP ports from 2xxx to 21xxx “I don’t remember that exact number” I ready the comments regarding this “ that each 4 UDP ports will used for one CTI Ports” I checked CUAC Admin Guide and I can see that UDP ports for Media start from 50000 to 52000, and I change it in TAPE installation to this ports and working 100%.
This Document is not official answer and maybe there is other work around for this issue, but it’s working with me like this.
We are facing an issue with CFA. When a user forward all calls to an external number and he receive an internal call everything is working fine meaning that the internal call is being forwarded normally to the external number. But whe...
I'm not able to make outgoing calls, the first thing you hear is a busy tone.
Call attempt is stopped immediately.
Please find attached 2 test results in the attachment.

We have quite a few codecs (approx 80 SX80s and SX20s). Is there any easy way to deploy and manage certs to codec endpoints (these are all running CE9). It would be a pain to have to load them all by hand and update them all by hand when they expire.
