[cisco-voip] SIP Caller ID issue

[Mike]

Hi all , I have a situation where the carrier (XO) is not allowing the call
manager to send caller ID if it's not a number assigned to the trunk. In
this situation the main number is not on the sip trunk its on a PRI. The XO
tech said you can get around this by modify the SIP header in the from
field. Anyone ever ran into this?

 

Thanks,

Mike
