4000 Router Series Voice Command Reference

• MFC—The originating and terminating sides use interregister signaling to transmit and request

number information, including the calling number, line information, and billing. In the exchange

process, the terminating side sends responses to the originating side.

• DTMF—The originating side transmits the called number to the terminating side digit by digit. The

terminating side does not send any responses for confirmation.

Compared with the MFC mode, the DTMF mode has a faster connection speed but transmits a smaller

amount of information.

You must configure the same mode on the originating and terminating devices. Otherwise, the two sides

cannot establish any calls.

Usage guidelines

R2 interregister signaling in some countries requires the originating side to send a number terminator

after sending the called number. You can configure the final-callednum enable command to meet the

requirement. After the terminating side receives the terminator, it stops requesting the called number.

Examples

# Configure the originating side to send a number terminator to the terminating side after sending the

called number.
