In CUCM, I need to implement a solution where the digit 9 is automatically prefixed on all calls from WebEx to NADP (1+10digits) numbers, but do NOT prefix digits for 3-digit internal extensions. When manually dialing a 9, outbound calls work great, but is not acceptable as a deliverable solution for the WebEx "call me" feature.
What is the best way to do this? With Jabber, I simply used an application dial rule, but with WebEx, its essentially a SIP trunk, so that feature is not available.
CUCM 9.1, WebEx 1.1.1.9
