PBX Integration

Integrating FaxPress network fax server with your PBX. FaxPress can be easily integrated with most PBX phone systems to provide automatic routing and delivery of incoming faxes to the recipient's email mailbox or desktop with DID (Direct Inward Dialing). With DID each user or department has an individual fax number from the organisations DID range. Depending on model, an Open Text fax appliance can be connected to the following types of port / line on the PBX: -

• Analogue
• Digital
• ISDN2 (Also called BRI, Basic Rate ISDN)
• E1 (Also called ISDN30, PRI, Primary Rate ISDN)
• Fax-over-IP

Digital connection ISDN2 (Basic Rate ISDN) and E1 (Primary Rate ISDN30) connections support Digital DID as standard. Typically very little configuration is required on the PBX or FaxPress system to set this up.

FaxPress Enterprise systems connect directly to the digital lines / ports on the PBX: -

FaxPress 2500, FaxPress Desktop and FaxPress Premier systems can be connected to ISDN2 digital ports/lines with Chiron Connect 200 ISDN Converters: -

Analogue connection Many PBX’s support Analogue DID. FaxPress 2500, FaxPress Desktop and FaxPress Premier systems monitor for touch tones (DTMF) sent by the PBX, and then receive the incoming fax, later routing it to a specific user’s fax box that corresponds to the DTMF tones the FaxPress received at the start of the call. The sender of the fax simply enters a regular fax number and the FaxPress automatically delivers the fax to the correct mailbox (network user, printer, email address or customer application).

Most PBX’s are compatible with FaxPress’s Analogue DID support, because it is similar to the way many voice mail systems operate. Most PBX’s can be configured to support multiple voice mail systems. The PBX sees the FaxPress as a second voice mail system.

The PBX will need to be programmed to have the analog ports connecting to the FaxPress setup in their own hunt group. The analog ports in this group need to be programmed with voice mail attributes, so that when incoming calls are received, DTMF is transmitted prior to connection to the FaxPress. When the call comes in on the DID, the phone switch assumes that it is call forwarding it to a voice mail system and transmitting the mailbox number. Actually, the FaxPress is answering the incoming call that has been forwarded, detects the DTMF and receives the fax.

In the example above, the FaxPress 2500, FaxPress Desktop or FaxPress Premier receives ring voltage, then answers the line and waits a few seconds, monitoring for DTMF tones to identify the fax recipient. If the FaxPress or FaxPress Premier system receives DTMF tones that are a match to the programmed database, the fax server will return a fax handshake tone that signals the sending fax terminal to begin transmission. If no DTMF or incorrect DTMF tones are received, the FaxPress or FaxPress Premier will either hang up, or send the fax to the Unaddressed user account.
