Frequently asked question

Why is there a pause before my ATA phone call goes through?

When you make a call with your ATA device using VoIP, there’s usually a 4-second delay after you dial a number. Since VoIP calls go over the internet, the process is more complex than with regular phone lines, which causes this delay.
