DID Tab

1. Numbers must be listed in 10 digit format. Do not include the 1

Note: The 3CX's template for our platform uses "From User" under Caller Name. This is to avoid an issue where calls to the PBX without a Display Name will show the Display Name as blanks on the phone. Otherwise, selecting "From: Display Name" will force the PBX to use the CID Name on the Display Name of the phones. Please use the setting that is appropriate for your setup.
