designated in a gateway group.

Explanation:
In the same way as when connected by a TIE Line, if a dialed number is not found at the local PBX, the call
can be sent to other PBXs connected via an IP network. When an extension number is dialed, the PBX first
searches local extensions for a matching number. If there is no match, the PBX then checks the TIE Line
Routing Table for the Gateway Group for a corresponding entry. If an entry is found, the call is sent to the
connected PBX.
Automatic Rerouting of VoIP Calls to Public CO Lines
When a VoIP call cannot be completed successfully, the PBX can automatically attempt to make the call using
a public CO line instead. This provides a backup method of making calls in cases when IP network transmission
cannot be completed successfully.
