Callmanager 4.1 – No Answer Ring Duration
If you want a line to ring X amount of time before it rolls elsewhere you need to edit two things.
Add the extension to send the caller to in “Forward no Answer” section.
You then need to edit the “No Answer Ring Duration” section. This entry sets the number of seconds to wait before transferring. This defaults to 12 seconds which almost gets you 3 rings. I usually want right at 6 rings, so I set the timer for 30 seconds.
Traditionally, 1 ring = 4 seconds
