1. Introduction
These Application Notes describe the procedures for configuring Open Text Fax Server, RightFax
Edition with Avaya Aura
®
Communication Manager and Avaya Aura
®
Session Manager using SIP trunks.
Open Text Fax Server, RightFax Edition is a software based fax server that sends and receives fax calls over an IP network. Open Text Fax Server, RightFax Edition utilizes the Brooktrout SR140
T.38 Fax over Internet Protocol (FoIP) virtual fax board software from Dialogic. In the tested configuration, Open Text Fax Server, RightFax Edition interoperated with Avaya Aura
®
Session
Manager to send/receive faxes using a SIP trunk interface.
1.1. Interoperability Compliance Testing
The compliance test tested interoperability between RightFax and Session Manager by making intrasite and inter-site fax calls to and from a RightFax server that was connected (at each of the two sites in the test configuration) to Session Manager via SIP interface. Specifically, the following fax operations were tested in the setup for the compliance test:
Fax from/to RightFax to/from fax machine at a local site
Fax from/to RightFax to/from fax machine at a remote site
Fax from/to RightFax to/from RightFax server at a remote site
In the compliance test, both ISDN-PRI trunks and SIP trunks directly connecting two
Communication Manager systems connected the Main Site, and Remote Site.
Faxes were sent with various page lengths and resolutions. For capacity, a large number of 2-page faxes were continuously sent between the two RightFax servers. Serviceability testing included verifying proper operation/recovery from failed cables, unavailable resources, restarts of Session
Manager as well as RightFax reboots. Fax calls were also tested with different Avaya Media
Gateway media resources to process the fax data between locations. This included the TN2302AP IP
Media Processor (MedPro) circuit pack and the TN2602AP IP Media Processor circuit pack in the
Avaya G650 Media Gateway; the integrated Voice over Internet Protocol (VoIP) engine of the
Avaya G450 Media Gateway, and the Avaya MM760 Media Module installed in the Avaya G450
Media Gateway.

2. 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. Figure 1 illustrates the configuration used in these Application Notes.
2.1. Configuration Details
In the sample 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 RightFax servers communicated directly with Session Manager via SIP.
Two separate Session Manager Servers were used to connect the RightFax Servers to each site.

Figure 1: RightFax interoperating with Session Manager via SIP Trunk
The Main Site had an Avaya S8800 Server running Communication Manager with two Avaya G650
Media Gateways. Each media gateway was configured as a separate port network in separate IP network regions. The RightFax 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 4600 Series IP
Telephone (with H.323 firmware), and an analog fax machine.
The Remote Site had an Avaya S8300 Server running Communication Manager in an Avaya G450
Media Gateway. The RightFax 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 the effect VoIP telephone calls had on the FoIP faxing operations.
Outbound fax calls originating from RightFax 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 RightFax 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 RightFax via the configured
Session Manager SIP trunks.

3. Administer IP Network Region 1
Description
The configuration of the IP network regions (Steps 3 – 6) was already in place and is included here for clarity. At the Main Site, 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.
At the Remote Site, all IP components were located in IP network region 1 and the IP network region was configured in the same manner as shown below. display ip-network-region 1 Page 1 of 20

Session Manager and the RightFax server were configured to be located in an IP network region other than the default region 1; the region was assigned using the change ip-
network-map command. In the case of the compliance test, the IP addresses for these resources at the Main Site were assigned to IP network region 2 as shown in the example below. At the Remote Site, Session Manager and the RightFax server were located in the default IP network region 1, so it did not require an IP address map entry. change ip-network-map Page 1 of 63

10. Administer IP Codec set – Fax settings
On Page 2, set the FAX Mode field to t.38-standard. This is necessary to support the
RightFax server assigned to IP network region 2. The Modem Mode field should be set to off.
Leave the FAX Redundancy setting at its default value of 0. A packet redundancy level can be assigned to improve packet delivery and robustness of FAX transport over the network (with increased bandwidth as trade-off). Avaya uses IETF RFC-2198 and ITU-T
T.38 specifications as redundancy standard. With this standard, each Fax over IP packet is sent with additional (redundant) 0 to 3 previous fax packets based on the redundancy setting. A setting of 0 (no redundancy)
is suited for networks where packet loss is not a problem
. This setting should match the redundancy settings in Brooktrout SR140 configuration; otherwise Brooktrout SR140 will negotiate T.38 redundancy to the most common denominator (no redundancy in this case). change ip-codec-set 1 Page 2 of 2

11. Administer SIP Signaling Group
Description
For the compliance test, a signaling group and the associated SIP trunk group was used for routing fax calls to/from the RightFax server via Session Manager. For the compliance test at the Main Site, signaling group 12 was configured using the parameters highlighted below. All other fields were set as described in [3].
The Group Type was set to sip.
The Transport Method was set to the recommended default value of tls (Transport
Layer Security). As a result, the Near-end Listen Port and Far-end Listen Port are automatically set to 5061.
The Near-end Node Name was set to CLAN2A, the node name that maps to the IP address of the CLAN circuit pack used to connect to Session Manager. Node names are defined using the change node-names ip command (see Step 7 above).
The Far-end Node Name was set to demoSM. This node name maps to the IP address of the Session Manager server as defined using the change node-names ip command.
The Far-end Network Region was set to 2. This is the IP network region which contains Session Manager and RightFax.
The Far-end Domain was set to avaya.com. This domain is sent in the headers of SIP
INVITE messages for calls originating from and terminating to Session Manager using this signaling group.
Direct IP-IP Audio Connections was set to y. This field must be set to y to enable
Media Shuffling on the trunk level (see Step 3 on IP-IP Direct Audio).
The DTMF over IP field was set to the default value of in-band.
The default values were used for all other fields. change signaling-group 12 Page 1 of 1

Session Manager - Overview
This section covers the configuration of Session Manager at the Main Site. Session Manager is configured via an Internet browser using the administration web interface. It is assumed that the setup screens of the administration web interface have been used for initial configurations. For additional information on these installation tasks, refer to [3].
Each SIP endpoint used in the compliance test that registered with Session Manager required that a user and endpoint profile be created and associated with Session Manager. This configuration is not directly related to the interoperability of the products being tested, so it is not included here. These procedures are covered in [3].
This section summarizes the configuration steps that are necessary for interoperating with RightFax.
The test environment was previously configured to enable Communication Manager and Session
Manager at each site to communicate with each other. Details of this configuration are not described in this document, and additional information can be obtained in [3].
The documented configurations were repeated for the Session Manager at the Remote Site using values appropriate for the Remote Site from Figure 1. This includes but is not limited to the IP addresses, SIP domain and user extensions.
The steps used were:
Create a SIP Entity for the RightFax Server
Create a SIP Entity Link for the RightFax Server
Create a Routing Policy
Create or Modify Dial Patterns

6.
Create or Modify Dial Patterns
Associating a dial pattern with a SIP Entity Link instructs Session Manager how to route calls matching the administered Dial Pattern(s). In the test, existing Routing Policies were modified for routing to endpoints or Entities at the Remote Site, and new Dial
Patterns were created to route to the Main Site and Remote Site Fax Servers using the existing and new routing policies.
In the snapshot below, the Dial Patterns were previously created. The applicable patterns were all 5 Digit extension patterns; dialed numbers beginning with 2 (the local analog fax machine at the Main Site), dialed numbers beginning with 40 (to route incoming Fax calls to the RightFax server at the Main Site), dialed numbers beginning with 45 (to route to Communication Manager at the Main Site in order to route via the public network interface between the sites). In addition, an existing 4 digit patterns beginning with 60 was used to route Fax calls to Communication Manager at the Main Site for routing via the public network interfaces to the analog machine at the Remote Site.
The ‘40’ and ‘45’ dial patterns were created for this test, all others were in place in the test environment.

6. Configure SIP IP Parameters
Important: This step describes configuring the SIP Primary Gateway address using the
Brooktrout Configuration Tool. This method is sufficient if the RightFax Server will communicate with a single SIP gateway or Session Manager. Alternatively, use
RightFax Dialing Rules, described in steps 10-11 below, to specify the address of the SIP
Gateway. You should only use one of these options. Do not use both.
Either option listed above is appropriate if Media Shuffling is enabled in the Avaya communications equipment.
If the RightFax Server needs to be configured to communicate directly with multiple gateways or Session Managers, use only RightFax Dialing Rules. Use a separate
Dialing Rule for gateway.
Navigate to Brooktrout IP Call Control Modules SIP in the left navigation menu. Select the IP Parameters tab in the right pane. Configure the fields as follows:
Primary Gateway –set to the IP address of the Session Manager server, and port number 5060.
From Value – set to appropriate UserInfo@DomainName. The DomainName should be set to the authoritative domain as configured in Session Manager.
Contact Address – set to the IP address assigned to RightFax and the port number 5060.
Username – Required. Default value is a dash („-„) character.
Use default values for all other fields.

7. General Test Approach and Test Results
This section describes the compliance test approach used to verify interoperability of Open Text Fax
Server, RightFax Edition with Avaya Aura
®
Session Manager.
7.1. General Test Approach
The general test approach was to make intra-site and inter-site fax calls to and from RightFax. 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 2page faxes were continuously sent between the two RightFax servers simultaneously. Serviceability testing included verifying proper operation/recovery from failed cables, unavailable resources, and
Session Manager and RightFax 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.
7.2. Test Results
Open Text Fax Server, RightFax Edition successfully passed all compliance testing.
7.3. 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.
