[asterisk-ss7] MSC NUMBER INSTEAD OF CALLER ID

Tue Feb 23 03:45:46 CST 2010

This is the MSC script/config if I understand yourr qustion correctly. I don't know which MSC you are connected to, but most of the switches are capable of replacing/manipulating IAM contents as needed. So talk to a switch engineer and get them to change this on he MSC side.
