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 #0 and the trunk number), the system drops the trunk if dial tone does not occur. If the user
accesses the trunk via a Trunk Group (by dialing a trunk group code or automatically using a feature
like Last Number Redial), the system can drop the trunk or optionally skip to the next trunk in the
group. Refer to the chart under Programming for more information.
