I am in the need of a solution for our extension 4724 to be able to forward to a third party that has an 888 number.
If I enter in the Forward All field (Directory Number Configuration) a none 800 number it works fine. The problem is with the 800 number.
I had AT&T fixed the problem by having them do the caller ID in their router. But it was not a good solution for all the other extensions as per company policy...
I read that by manipulating "Diversion Headers" you can fix this but we don't use SIP, I find it related to SIP everywhere. I think that I need to create a translation pattern for that extension. Here is when you come in. What is involve in doing so and Am I correct...
We have it like this here: AT&T router <--> Our Cisco router <---- > Call manager 8.5.1
