PROJECT NAME: Globstorm (IMS).Avaya has developed IMS compliance products such as Avaya Session Manager (P/I/S-CSCF), SIP Application server (SIP-AS), AAC conferencing server. Avaya Session Manager consists of three main components: P-CSCF called L-Home (Local Home/BSM), I-CSCF called SRE (SIP Routing Element) and S-CSCF called URE (user Relation Element).Performance (Load/Endurance/Soak/Stability) Testing: Avaya has developed a complete software based multi threaded performance simulation tool called Virtual Fabric Manager (VFM) that can simulate Avaya PBX, Media resources like Media processor, CLAN, crossfire board, processor card, E1/T1 etc) and TDM traffic..PROJECT NAME: Avaya Aura Audio & video conferencing server (AAC): Avaya has developed world class audio & video conferencing server called AAC (Avaya Aura conferencing) based on RFC 4575 (CCMP floor control protocol) and RFC 4579 (Conference factory uri) that supports H.263-1996, H.263-1998, H.263-2000 and H.264 video codec.Video gateway interoperability testing: Avaya has also developed world class Video gateway called Scopia Video gateway, Avaya also developed SIP based video tablet (ADVD) and Avaya Flare experience in collaboration with third party vendors such as Life-Size, Polycom and Tandberg.•Interoperability testing of Avaya ADVD & Flare video soft client with Tandberg, Life Size.•Video Codec Negotiation testing, video transcoding with H263-1996, H263-1998 and H263-2000•Validated CIF, QCIF, 4CIF, SQCIF, 16CIF and MPI for Video quality testing.Virtualization: Avaya Application server support both XEN (para-virtualization 3.1) and VMware ESX/ESXi 4.1 hypervisor and can supports utmost 5 virtual machines on a single host machine.•Installed & configured XEN Para-virtualization-PVM (XEN Hypervisor) virtualization layer.•Created privileged Virtual Machine (dom-0) called Virtual System Platform (VSP).•Created un-privileged VM (udom) and installed Avaya unified templates (CM, CMM and BSM)

ISUP loop back and IN/CAMEL based Optimal Routing or so call 'Least Cost Routing" is a network operator option whether to implement optimal routing for basic mobile-to-mobile calls.The existing UMTS and GSM architectures support the primary technical requirement of optimal routing for mobile to-mobile calls (basic OR): that a GMSC can interrogate an HLR in a different PLMN to obtain routing information for a mobile terminated call. Three logically distinct PLMNs are involved in the handling of an optimally routed mobile-to-mobile call:Prepared Least Cost Routing Test plan based on 3GPP TS 23.079 specifications.Taken complete ownership for LAB designing and product (LCR) testing for Maxis Telecom, Malaysia and Grameen Telecom, Bangladesh. Protocols Used: ISUP, SCCP, TCAP, MAP and CAMEL protocol.Components: MAP server, CAMEL network server and LCR (OR) application.Automation Tool and SS7 stack Used: Tektronix K-1297-G20 and DK-Septel SS7 stack.
