Hi all. I have an issue where a customer has several PRIs and when a internal caller calls out, they get a different caller ID mask, according to which PRI they hit. I have it set on the route pattern (in callmanager 6.x) to use a particular number when it hits that particular route pattern. But, it doesnt seem to work and I always get the same results no matter what. The same 4 numbers come up every time, depending on which of the 4 PRIs you hit. I have tried to call the carrier and they tell me they are not doing call masking at all. But I think they are because I have never seen the numbers that show up. So, I know I didnt program it in. How can I do a test to prove this to the carrier that they are the problem?
Hey, did the debug isdn q931 and it shows the number going out as the number I programmed in. But, on my caller ID of the phone Im calling, it still says something different each time, according to which PRI it hits. Is it safe to assume with this test that its the carrier?
