Is there anything on a sub ICS that controls outbound DID or what the called party sees . I have a system that has shown in example. 212-xxx-1234. Now all out bound calls show 646-xxx- 4567. Yes we have 646 numbers but none are programmed .
That could be what the CO is sending. You could try going into each set and set the OLI -outgoing line identification - If that dosen't work you have to call the CO and have them Let you pass the CLID.
