Replacing CallerID for a 911 trunk

[Clint Reed]

Hi All,

I am setting up a trunk for routing 911 calls out. I have the trunk up and running, My issue is with the Caller ID, I have a select group of phones that will display their DID when you dial out the normal trunk. If they would dial 911 my outbound rule switches to the linked trunk. What pattern in the Siptrunk> Caller ID Outbound pattern do I need to strip their caller id set on the extension and replace it with the main office number?

I tried a bunch of patterns trying to follow 3cx example page and it still sends the extensions caller ID out.

Thanks
Clint

On a separate trunk? Change outgoing "From : User Part" parameter.
