1. Introduction

These Application Notes describe the procedures for configuring Multi-Tech FaxFinder®IP Fax

Server with Avaya Aura®Communication Manager and Avaya Aura®Session Manager.

FaxFinder is an appliance-based fax server solution that sends and receives faxes over an IP

network. FaxFinder utilizes T.38 Fax over Internet Protocol (FoIP) for sending media. In the tested

configuration, FaxFinder interoperated directly with Avaya Aura®Session Manager to send/receive

faxes using SIP signaling.

2. General Test Approach and Test Results

This section describes the compliance test approach used to verify interoperability of Multi-Tech

FaxFinder® IP Fax Server.

2.1. General Test Approach

The general test approach was to make intra-site and inter-site fax calls to and from FaxFinder. The

inter-site calls were made using SIP or ISDN-PRI trunks between the sites. Faxes were sent with

various page lengths, resolutions, and at various fax data speeds. For capacity, a large number of

multi-page faxes were continuously sent between the two FaxFinder servers simultaneously.

Serviceability testing included verifying proper operation/recovery from failed cables, unavailable

resources, and Session Manager and FaxFinder restarts. Fax calls were also tested with different

Avaya Media Gateway media resources used to process the fax data between sites. This included the

TN2302 MedPro circuit pack, the TN2602 MedPro circuit pack in the Avaya G650 Media Gateway;

the integrated VoIP engine of the Avaya G450 Media Gateway and the Avaya MM760 Media

Module installed in the Avaya G450 Media Gateway.

2.2. Test Results

Multi-Tech FaxFinder® IP Fax Server successfully passed compliance testing.

2.3. General Observations

Fax calls consume DSP (Digital Signal Processing) resources for processing fax data on the

TN2302AP IP Media Processor (MedPro) circuit pack and the TN2602AP IP Media Processor

circuit pack in the Avaya G650 Media Gateway, and the integrated Voice over Internet Protocol

(VoIP) engine of the Avaya G450 Media Gateway. To increase the capacity to support simultaneous

fax calls, additional TN2302AP and/or TN2602AP MedPro circuit packs need to be installed in the

Avaya G650 Gateway, and additional Avaya MM760 Media Module or Modules need to be installed

in the Avaya G450 Media Gateway. The information contained in the table below indicates DSP

capacities/usage in the Avaya media processors. Customers should work with their Avaya sales

representatives to ensure that their fax solutions have adequate licenses and DSP resources to match

the intended Fax capacity/usage.

Note that the SIP trunk group on Communication Manager for connecting to Session Manager at

each site, as well as the SIP or ISDN-PRI trunk group for connecting the 2 sites must be configured

with adequate number of trunk group members to support the number of simultaneous fax calls

intended.

3. Configuration

The test configuration was designed to emulate two separate sites with multiple Port Networks at

one site, and modular Gateway resources at the other site. Each site was configured with Multi-Tech

FaxFinder®IP Fax Server, Avaya Aura®Communication Manager and Avaya Aura®Session

Manager. Figure 1 illustrates the configuration used in the tested configuration.

3.1. Configuration Details

In the tested configuration, Communication Manager Servers and Gateways at the two sites were

connected via SIP and ISDN-PRI trunks. Faxes were alternately sent between the two sites using

these two facilities. Connections to Session Manager were via SIP trunk facilities, and the FaxFinder

servers communicated directly with Session Manager via SIP.

Two separate Session Manager Servers were used to connect to the FaxFinder Servers at each site.

Figure 1: Multi-Tech FaxFinder®IP Fax Server sample configuration

Site A had an Avaya S8800 Communication Manager Server with two Avaya G650 Media

Gateways. Each Media Gateway was configured in a separate port networks with separate IP

network regions. The FaxFinder server at this site communicated with Session Manager via SIP. In

turn, Communication Manager used a SIP Trunk which terminated on a CLAN circuit pack in port

network 2 to communicate with Session Manager. IP media resources were provided by Media

Processor (MedPro) circuit packs. Two versions of the MedPro circuit pack were tested in this

configuration: TN2302AP and TN2602AP. Endpoints at this site included an Avaya 9600 Series IP

Telephone (with H.323 firmware), and an analog fax machine.

Site B had an Avaya S8300 Communication Manager Server in an Avaya G450 Media Gateway.

The FaxFinder server at this site communicated with Session Manager via SIP. On the Avaya G450

Media Gateway, the signaling and media resources supporting a SIP trunk connected to Session

Manager were integrated directly on the media gateway processor. Endpoints at this site included

Avaya 9600 Series IP Telephones (with H.323 and SIP firmware), and an analog fax machine.

The IP telephones were not involved in the faxing operations, they were present in the configuration

to verify that VoIP telephone calls did not interfere with FoIP faxing operations.

Outbound fax calls originating from FaxFinder were sent to Session Manager first, then to

Communication Manager, via the configured SIP trunks. Based on the dialed digits, Communication

Manager directed the calls to the local fax machine, or the inter-site trunks (ISDN-PRI or SIP) to

reach the remote site. Inbound fax calls to FaxFinder were first received by Communication

Manager from the local fax machine or from across either ISDN-PRI or SIP trunks connected to the

remote Site. Communication Manager then directed the calls to FaxFinder via the configured

Session Manager SIP trunks.

Administer IP Network Region 1

The configuration of the IP network regions (Steps 3 –6) was already in place and is

included here for clarity. At Site A, the Avaya G650 Media Gateway comprising port

network 1 and all IP endpoints were located in IP network region 1.

Use the display ip-network-region command to view these settings.

A descriptive name was entered for the Name field.

IP-IP Direct Audio (Media Shuffling) was enabled to allow audio traffic to be sent

directly between IP endpoints without using media resources in the Avaya Media

Gateway. This was done for both intra-region and inter-region IP-IP Direct Audio.

This is the default setting. Media Shuffling can be further restricted at the trunk level

on the Signaling Group form.

The Codec Set field was set to the IP codec set to be used for calls within this IP

network region. In this case, IP codec set 1 was selected.

The default values were used for all other fields.
