[Asterisk-Users] Revert to dial tone?

[Greg Blakely]

I am wondering if it is possible for an extension that is served by a
zaptel device to revert to dial tone once a call disconnects.

For instance, if I make a call to another extension, talk with them, and
THEY hang up, can I then be presented with a new dial tone rather than a
congestion tone?

Further, can an extension be set up so that, once the call goes back to
dial tone, if the user does NOT dial any digits within a timeout period,


+  the PBX will return 30 seconds of congestion tone, and then
+  the PBX will return 60  seconds of "howler" tone, and then
+  the extension is 'locked out.'

?

Thanks.
