Sometimes a single user will need their own outbound Caller ID – for instance, if the user has their own private DID. This Tech Tip will demonstrate how to change a displayed caller id number on an outbound call made from the NEC SL200 or NEC SL1100. (IP extensions only)
Get Connected
This procedure requires access to the NEC SL2100 using the PCPro Programming Software.
To download PCPro or learn how to connect to the phone system, refer to:
