Thanks Jason and devildoc. My original question was which kicks in first and which kicks in at the last. I do have the book Devildoc has referred but it doesn't tell you the sequence.
Incoming calls: 1. hits GW, if significant-digit is set to 4 , it will pass only 4 digit to CCM 2. Now if the CCM also has xlation pattern, will 4 digits coming from GW significent digit will hit xlation pattern? Same thing what will be for outgoing calls? 1. transformation-mask > Route-pattern first > then Xlation pattern > ? What about application dial-in rules? Frog
