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 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.
