The Uniform Dial Plan (UDP) call type works identically with the ext call type, with an exception: if the dialed digits match the call type of UDP, Communication Manager automatically checks the UDP table to see if there is a match, regardless of the value in the UDP Extension Search Order field on the Dial Plan Parameters screen. If there is no match, Communication Manager then checks the local server.

If the dialed digits match the call type of ext, Communication Manager checks the value in the UDP Extension Search Order field on the Dial Plan Parameters screen.

If the value in the UDP Extension Search Order field on the Dial Plan Parameters screen is udp-table-first, Communication Manager checks the UDP Table first to see if there is a match. If there is no match, Communication Manager then checks the local server.

If the value in the UDP Extension Search Order field on the Dial Plan Parameters screen is local-extensions-first, Communication Manager checks the local server first to see if there is a match. If there is no match, Communication Manager then checks the UDP table.

The UDP call type allows Communication Manager to recognize strings of 14 to 18 digits, which are longer than the maximum extension length of 13 digits. However, the UDP call type can be used with any length in case this provides a useful new capability to customers.

UDP in System Manager

You can select the Uniform Dial Plan option on the Synchronize CM Data and Configure Options page from Elements > Communication Manager > System > Uniform Dial Plan Groups. When you select the Consider UDP option, the system does not use the corresponding dial plan for the available extension range while adding an endpoint. When you do not select the Consider UDP option, the system uses the corresponding dial plan for the available extension range while adding an endpoint.
