SBC 5100 is a robust solution that integrates security, call control, Quality of Service, advanced media services and switching all within a compact platform. SBC 5100 functionality was compliance tested using a SIP trunk to Mitel 3300 Integrated Communications Platform. The objective of the document is to describe the procedure to be followed during Interoperability Testing (IOT) of SBC 5100 with Mitel 3300 Integrated Communications Platform. It includes identifying the testing environment, tools, topology, points, risks, and scope.

Audience This technical document is intended for telecommunication engineers with the purpose of configuring both the Sonus SBC and the third-party product. There will be steps that require navigating the thirdparty and Sonus SBC Command Line Interface (CLI). 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 Sonus Networks • SBC 5100 • BMC • BIOS • ConnexIP OS • SonusDB • EMA • SBX Third-party Equipments • Mitel 3300 PBX • SIP Phones • POTS Phones 3.0.0R000 V2.0.0 V2.0.0 1.8.0-A7 sonusdb-V03.00.00-A011 ema- V03.00.00-A011 sbx- V03.00.00-A011 4.2 SP2 (10.2.2.10) Other software 2.3. Test Scenario SIP trunks were used to connect SBC 5100 to the enterprise site and to a simulated PSTN/Service Provider. The following features and functionality were covered during compliance testing: 4 of 42 • Incoming calls to the Enterprise site through the SBC 5100 • Outgoing calls from the Enterprise site through SBC 5100 • Calls using various analog, digital and SIP endpoints supported by the Mitel 3300 PBX solution • Calls using various codecs Sonus Networks Interoperability Test Lab • Inbound and outbound fax calls • DTMF tone transmission using RFC 2833 with successful voice mail navigation • Telephony features such as hold, resume, transfer, conference, and call forwarding. Serviceability testing focused on verifying the ability of SBC 5100 to recover from adverse conditions, such as disconnecting/reconnecting the Ethernet cable and stopping/starting Sonus Networks SBC 5100 and Mitel 3300 PBX. 2.4. Reference Configuration A simulated enterprise site consisting of Mitel 3300 PBX, Session Manager, System Manager, and SBC 5100 version 3.0 was used during compliance testing. SIP trunks were used to connect SBC 5100 with Communication Manager via Session Manager. SBC 5100 was also connected to a simulated PSTN/Service Provider via a SIP trunk. The configuration allowed the enterprise site to use SIP trunking for calls to and from the simulated PSTN/Service Provider via SBC 5100. The following reference configuration shows connectivity between third-party product and SBC 5100. Figure 1 Sonus SBC 5100 with Mitel 3300 2.5.
