Appointment reminder call lines

If there are times, when I only want to call out using only 1 phone line instead of the 2 phone lines, is there anything I can do to just set it to call out on 1 line?

You can go to Voicent Gateway and disable one of the lines. For example, if you use modem, select the Modem tab of gateway setup options.

There is no other control for selecting lines.

You could control how many calls are allowed on a particular line. For example, you can set to make 1 call every 10 minutes. This is called “interval dialing”, and it can be set under gateway options too.
