We’re currently using a UCM6202 IP-PBX and have two FXO Lines on it. Is there a way to set it up where, with the press of a button (say, dial 0), it auto-selects which of these two lines is currently available? other vendors even gives one the option to do a “round robin” if both FXO lines are available at the time.
example: the user (who wishes to make outbound calls) dials 0, waits for a dial tone (as a signal that the pbx system has already selected an available FXO line, then dial the actual telephone number to make that call.
TL;DR - in order to make a call, one needs to dial a prefix code first (preferably “0”) and wait for the dial tone before dialing the phone number.
Appreciate your responses!
