I want to create a new routing pattern for the SIP trunk,
Right now I am using routing pattern of 6[^5]XXX in my CUCM, means except 65XXX series should goes to Nortel system through E1. But now i need to remove 60XXX series from this routing pattern. I am going to use 60XXX as a pattern for SIP trunk. So how to split this route pattern 6[^5]XXX.
Anyone can help me to split this routing pattern 6[^5]XXX correctly.
