System Configuration 119

Synapse Installation Guide

Using the fax line for outgoing calls is not restricted, but the caller ID of the fax number, not the primary business telephone

number, will be sent as caller ID. This may result in some confusion if the recipient returns a missed call via their caller ID Log as

they will then experience the eight-second delay mentioned above. Callers who return calls to DID telephone numbers will be

calling your fax machine.

If your fax machine has an integrated telephone, you cannot use that telephone for incoming or outgoing phone calls.

You cannot start a call in voice mode then change to fax mode.

Fax Configuration

A fax machine can be connected to one of the FXS ports on the ATA, as shown in Figure 128. Incoming fax transmissions are

routed from a telephone connection on the Gateway over your LAN and through the ATA to your fax machine. Similarly, faxes

travel from your fax machine through the ATA and over the LAN to the Gateway for transmission to the far-end fax machine.

You must select a PSTN Gateway line or a DID number as your fax line. This is done in Fax Configuration in the WebUI.

The ATA supports two modes for fax transmission: G.711 and T.38.

 G.711 is a pass-through method that is the older, simpler fax protocol. G.711 mode provides the best compatibility with

most fax machines and therefore is the default mode.

 T.38 is the standard protocol for faxing over IP networks and is more resistant to network impairments. However, users

will not hear Call Progress Tones (CPT) such as ringback and busy signals. Fax machine compatibility issues are common.

T.38 is not available if the fax telephone number is through the T1 Gateway.

Before dialing a fax number, you must dial a 9 or whatever digit, if any, that must be dialed first for an outside call.
