To configure DTMF routing options for a fax board, click the Routing tab of the device Properties dialog box.
With Dual-Tone Multi-Frequency (DTMF) routing, each dialed digit is represented by two tones to provide protection against false digits appearing during transmission due to noise. In respect to faxing, DTMF means that the sender of the fax must enter additional numbers (i.e., the recipient's fax extension number) when prompted by the receiving fax machine or device. Because there must be some coordination between the sender and the recipient, this routing mode is not as popular as DID/DNIS.
The general steps for configuring FACSys DTMF routing are the following:
| • | Use the manufacturer supplied utilities for configuring the board's DTMF routing options. |
| • | In the FACSys Administrator device's Properties dialog box on the Routing tab, define the number of routing digits used in your configuration. |
| • | For every FACSys user that has a DTMF identification, you must enable inbound routing to the user and enter the user's routing ID in their FACSys user profile on the General tab. For instructions on defining general user account options. |
| • | To configure DTMF routing to a FACSys user group, you must enable inbound routing to the group and enter the group's routing identification code in the group Properties dialog box on the Routing tab. |
NOTES:
| • | To configure the DTMF settings properly, you must refer to the sending fax machine's documentation. You need to determine the correct settings for tone intervals and termination codes. This information will vary with every fax machine manufacturer and model. |
| • | The device you are configuring must support DTMF tone detection. |
