Each port that is available or unassigned is indicated by a u
. Choose an available port from a board type that matches your telephone type (such as a port on an analog board for an analog telephone). Every telephone must have a valid port assignment, also called a port address. The combined board number and port number is the port address. So, if you want to attach a telephone to the third port on the 01V2 board, the port address is 01V203 (01=Media Gateway, V2=Slot, 05=port).
Note:
If you add several telephones at one time, you might want to print a paper copy of the System Configuration screen.
