If you have office number assigned in “External Caller Id”, called person will see the number which is assigned in “External caller id “
You can set the “External Caller ID “- Users/Phones – Users- set the number in “External Caller ID “
Note: you should have valid DID number, which can be enter in External Caller ID.
