Using the Y Character

The "Y" character, used in the Telephone Number field when creating a short code, is designed to send the digits following the "Y" as DTMF tones. This option differs from the "D" option in that the digits following the Y in the Short Code are sent as DTMF tones on reception of either a Progress or Call Proceeding message from the Line Provider, whereas the "D" option sends the digits as DTMF tones only after a "Connect" message is received.

For example, the "Y" character would be necessary at a site where they have signed up with their telephone service provider to withhold long distance dialing until a DTMF pin/account number is entered that initiates the call progress/proceeding message.

The following example demonstrates how the Y character can be used.

Short Code: 91N;

Telephone: 1NY2345

Feature: Dial

In the above sample short code, 1 represents the long distance access, N represents the telephone number and 2345 represents the DTMF pin/account number.
