Dial Tone Detection
Description
If a trunk has Dial Tone Detection enabled, the system monitors for dial tone from the telco or PBX
when a user places a call on that trunk. If the user accesses the trunk directly (by pressing a line key or
dialing #9 and the trunk’s number), the system will drop the trunk if dial tone does not occur. If the user
access the trunk via a Trunk Group (by dialing a trunk group code or automatically through a feature like
Last Number Redial), the system can drop the trunk or optionally skip to the next trunk in the group.
