I believed what I want to do is call PRI Splitting
What happened is that my customer had one range of number:
64179500 to 64179519
now, the range is not enough, and the provider give them
65129500 to 65129519
How can i configure this on a CCME, so that CCME will recongnize both set of number and pass to the respective user?
First set of user extension: 500 - 519
Second set of user extension: 600 - 619
Is this possible?
