I have a CUBE configuration that is also acting as an internet gateway. Unfortunately applying a NAT to the interface destroys SIP and the gateway fails. Remove NAT and all is well. This is in a rural community in which they cant really afford mu...
I am attempting to export a CUCM Virtual Machine image to an AWS EC2 instance. Running into a number of challenges and am wondering if anyone else has tried it or has actually done it successfully? I would be interested in sharing experience and l...
Wrestling with a new deployment of CISCO Workforce (I even struggle with the name). Simple 10.6 CISCO UCCX and CUCM cluster and a single WFQ server for Compliance Recording only, no fancy features. I configured CUCM much the way I would configure ...

PSTN_IP=>(G0/0=>STATIC-NAT L0=>G0/1)=>LAN
Internet_IP=>(G0/0=>NAT Overload =>G0/1)=>LAN
