Trunk Group Night Service redirects all calls arriving over a split’s assigned trunk groups to an internal destination. The Night Service destination for the trunk group and the telephone button used to activate the feature are assigned through communication server administration.

Trunk Group Night Service by itself does not guarantee that all calls to a split will be redirected. Calls from local extensions and DID calls will still connect to the split.

Trunk Group Night Service and Hunt Group Night Service can both be active at the same time. If the Trunk Group Night Service is active, the destination is used for calls that come in over the trunk group even if the calls go to a split that has a Hunt Group Night Service destination assigned.
