Trunk Overflow

To learn more about pricing please contact a representative.

The Trunk Overflow feature automatically reroutes all inbound calls to another phone number when all channels in the trunk group are in use. This feature provides additional inbound calling capacity during peak calling periods when trunk capacity has been exceeded. Once call capacity within the trunk group becomes available, the feature automatically restores the standard routing of inbound calls through the PRI.
