Change an extension Caller ID for IP Trunk calls

[bajangerry]

Hi Guys,

Do anyone know if there is a way to mask the caller ID of an extension number for calls over IP Trunks similar to CPN Substitution for SIP calls? I have a number of extensions that I would like to show a different caller ID for when placing calls to another PBX via IP Trunks.

Thanks,
Gerry

I would think the only way would be to use a button and set the COS to allow the change based on DN

Thanks John, that would not solve the problem as I need this to be the actual extension's number, not a second number. I will just have to set the extension to Private instead as I can't find a way to do what they have requested.
