DID Configuration Setup

DID Configuration Setup
Overview
The SilentFax|DID configuration allows inbound faxes to be delivered to end-users’
mailboxes automatically. DID fax routing relies on the DID trunk service provided by the
Telco.
With the DID service, the Telco assigns a set of phone numbers to one or more DID
trunks. When a call comes into SilentFax server via a DID trunk, the Telco dials the digits
of the call dialed (referred to as the Dialed Number from now on). SilentFax receives the
Dialed Number digits and routes the incoming fax based on the Dialed Number.
Typically, instead of all of the Dialed Number digits, the Telco sends only last 4 or 3 digits
since these digits are the only relevant ones and are sufficient to identify the end-user for
which the call was intended. SilentFax server can easily be setup to convert the received
digits into an end-user mailbox number:
•
Tell SilentFax which part of the received digits represents an end-user mailbox,
•
•
Setup mailboxes to match the received digits,
Since DID trunks are receive-only trunks, configure the channels so that channels
connected to DID trunks won’t be used for outbound fax calls.
This document explains the setup process by providing two example scenarios.
As a convention, a double “>” is used to indicate user interface selections. For example,
Main Menu >> Channels would mean, “selecting the Channels option from the Main
Menu”.
If you are installing SilentFax behind a PBX system, you can jump to Page 4 for routing
examples.

Connecting Phone Lines
The SilentFax|DID configuration consists of DID interface cards and fax boards. The DID
interface card has two connectors per DID trunk. Its main function is to convert the DID
trunk characteristics into loop start (ordinary phone line) characteristics.
The figure shown below is the 4-port with 2 DID configuration:
•
Fax Ports 1 and 2 are connected to the DID trunk interface board and used for
incoming calls.
•
Fax Ports 3 and 4 are connected to loop start lines and used for outbound calls.

Configuring Channels (Ports)
Since DID trunks cannot be used for outbound calls, the channels connected to DID
trunks must be disabled for outbound calls.
•
Main Menu >> Channels
Disable Channel 1 and 2 for callouts

Setting up DID Routing - Example 1
In this example, we assume that the Telco sends the last four digits of the Dialed Number.
Let’s say 4000 through 4019, corresponding to your phone numbers 555-4000 through
555-4019, for example.
•
Main Menu >> Mailboxes
Create 4-digit mailbox numbers to match the DID digits,
•
Main Menu >> Routing >> DTMF Routing
Digit patterns are set up to map all received digits to a mailbox number.
•
Main Menu >> Routing >> DTMF Routing
Enable “DTMF/DID routing”

Setting up DID Routing - Example 2
In this example, we assume that the Telco sends the last four digits of the Dialed Number
just like the previous example, say 5400 through 5419. However in this example, we
would like to set up 3-digit mailbox numbers (for no good reason, just a preference).
Therefore, the first received digit must be ignored and the remaining three digits must be
used as the mailbox number.
•
Main Menu >> Mailboxes
3-digit mailbox numbers are set up to match the last 3 DID digits,
•
Main Menu >> Routing >> DTMF Routing
The digit pattern is set up to ignore the first digit (5 in this example) and map the
remaining three digits to a mailbox number.
•
Main Menu >> Routing >> DTMF Routing
Enable “DTMF/DID routing”
