2 Introduction The principle objective of Interoperability Compliance testing is to provide assurance to potential customers of the respective companies that the tested products will provide a suitable platform on which to build applications and business solutions.

2.1 Audience This is a technical document intended for telecommunications engineers with the purpose of configuring Sonus SBCs. Understanding the basic concepts of TCP/UDP, IP/Routing, and SIP/RTP are also necessary to complete the configuration and for troubleshooting, if necessary.

2.2 Requirements The following equipments and software were used for the sample configuration provided. Equipment

Software/Firmware versions

OpenText RightFax Server on Windows Server 2008 R2

Version 10.5 SR2 (Service Release 2)

Dialogic Brooktrout SR140 Fax Software (RightFax OEM)

SDK 6.3.4B11.51

Sonus SBC 1000/2000

Release 2.1v137

2.3 Test Scenario Testing between Sonus SBC 1000/2000 and OpenText RightFax was conducted by making inter-site fax calls to and from a RightFax server connected to Sonus SBC 1000/2000 through a SIP interface using T.38 Fax Relay and G.711 Fax Passtrough transport protocols. The following fax flow operations were tested in the setup for the compliance test: Fax from/to RightFax through a PSTN to/from fax machines at a remote site Fax from/to RightFax through PSTN to/from RightFax server at a remote site. In the compliance test, Sonus SBC 1000/2000 was connected to the PSTN using ISDN-PRI trunks.

2.4 Reference Configuration The test environment configuration was designed to emulate a single site running an OpenText RightFax server connected to a single SBC 1000/2000 media gateway. Figure 1: Interoperability between Sonus SBC 1000/2000 OpenText RightFax

2.5 Configuration Details In the sample configuration, OpenText RightFax 10.0 with Service Release 2 is installed and internally connected to an instance of SBC 1000/2000 media gateway through SIP Protocol, and enabled for both FoIP using both T.38 Fax Relay and G.711 Fax Passthrough. SBC 1000/2000 is connected to the PSTN through ISDN-PRI trunk. Calls were sent to/from another RightFax Server also connected to the PSTN through ISDN-PRI trunk, and to standalone fax machines connected to the PSTN using direct analog phone line or using ATA connecting to PSTN through another IP telephony network. Outbound fax calls from RightFax Server under test were first sent to the SBC 1000/2000 through SIP using both T.38 Fax Relay and G.711 Fax Passthrough transmission protocols. Calls from SBC 1000/2000 then traversed the PSTN to another RightFax server and to standalone fax machine destinations. Inbound calls from the PSTN were sent to the SBC 1000/2000 from the external RightFax server and standalone fax machines, which were then routed to the RightFax server under test over SIP using both T.38 Fax Relay and G.711 Fax Passthrough.

4 Phase II – OpenText RightFax Configuration This section describes the configuration of OpenText RightFax and the embedded Dialogic Brooktrout SR140 software. It is assumed that the application and all required software components, including Dialogic Brooktrout SR140 and the database software, have been installed and properly licensed. For instructions on installing RightFax, refer the RightFax Installation Guide. The configurations documented in this section pertain to interoperability between RightFax and SBC 1000/2000. The standard configurations pertaining to RightFax itself (for example, administering fax channels) are not covered. For instructions on administering and operating RightFax, refer the RightFax Administrator’s Guide.

4.1 Configuring RightFax Use the following steps to configure RightFax DocTransport Module. 1. Login to the RightFax Server or Remote DocTransport where the RightFax OEM FoIP (SR140) channels are to be configured. 2. The user must login using an account with Local Administrator rights. Note: Configuration of fax boards and FoIP channels must be performed from a session directly on the server that is hosting the telephony channels. 3. Open the RightFax Enterprise Fax Manager (EFM). 4. In the EFM window, select the RightFax Server or Remote DocTransport name from the left navigation pane.

4.3 Creating Dialing Rule(s) to route outbound faxes to the SBC 1000/2000 1. In the left-navigation pane of RightFax Enterprise Fax Manager, click Dialing Plan and then select Dialing Rules. 2. Right-click Dialing Rules and then click New. The Rule edit dialog box opens.

3. In the Rule Edit dialog box, configure an appropriate Pattern Match to route all phone numbers matching a specific pattern to the SBC 1000/2000. Note: This example uses a single Dialing Rule, with a plus sign (+) in the Pattern Match field, indicating that all fax calls will use this Dialing Rule to determine routing of faxes. 4. Click the Number Adjustments tab.

5. In the Append this field, enter @ symbol and the IP address of SBC 1000/2000 device to append this value to the dialing string of outbound faxes. This value instructs the RightFax DocTransport Module to direct outbound calls to the IP address specified. 6. Click OK to complete the Dialing Rule configuration.

7. In the RightFax Enterprise Fax Manager main window, click File and then click Save Dialing Plan to save the Dialing Rule configuration changes to the RightFax database.

5 Test Cases This section provides the details of verification tests performed to verify the interoperability between SBC 1000/2000 and OpenText RightFax.

5.1 Test Approach The general test approach was to place outbound calls of varying lengths and resolutions from the RightFax server under test, through Sonus SBC 1000/2000 to end points composed of other RightFax servers and standalone fax machines. Inbound calls of varying lengths and resolutions from these endpoints were also sent to the RightFax server under test through Sonus SBC 1000/2000. The Interoperability Test Plan included the following types of tests: Configuration and General Functionality - Configure the products and send faxes with various page lengths and resolutions. Feature Verification - Various features of RightFax and Sonus SBC 1000/2000 were tested. Serviceability Testing - Verify operation and recovery from failed cables, unavailable resources, and server reboots. Load Testing - Send a volume of varying legth faxes (for example, 2-page, 30-page and 100-page) over a sustained duration.

5.2 Test Results The Sonus SBC 1000/2000 successfully passed all compliance testing. General Observations OpenText RightFax 10.0 SR2 with Dialogic Brooktrout SR140 Fax Software only supports SIP over UDP Protocol. The Sonus SBC 1000/2000 media gateway with software release 2.1v137 supports maximum fax transmission speed of 14.4 kbps. V.34 is not supported in this release.
