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.
