Hi.. Im facing a very peculier problem..
Our network scenario:
1 cluster ( 3 CUCM ( 1 Pub, 2 Sub)
1 Gateway ( 2 PRI lines )
1 CUCM ( 3rd Subscriber)
1 Gateway ( 1 PRI Line)
I have a cisco ip phone 7960 with ext: 0311. I have also configured my Nokia E71 with the same extension using SIP.
All of sudden my phones started to ring with my own extension with some prefix which actually is not defined in Route Pattern.
For example.. my phones started ringing with 99197140311.
How is it possible.. ? Can anybody suggest how to rectify this issue..
