My extension number ringing on my phone with the prefix not defined at the route pattern or mask

Hi.. Im facing a very peculier problem..

Our network scenario:

Location 1:

1 cluster ( 3 CUCM ( 1 Pub, 2 Sub)

1 Gateway ( 2 PRI lines )

Location 2:

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..

Thanks you....

Question - did this start happening before or after you configured your Nokia SIP device with a shared extension?

This happened once after the nokia is configured for SIP...

So, it happened once - has it happened again? If not, I would be inclined to think it may have just been a quirk of having a shared line with a 3rd-party SIP device.
