Press Release: GL Enhances VoIP Conformance Testing for MGCP, MEGACO and SIP Protocols
Gaithersburg, Maryland, USA - August 18, 2009 - GL Communications Inc., announced today the release of enhancements to VoIP Conformance Testing for MGCP , MEGACO and SIP. During the press conference, Mr. Vijay Kulkarni, CEO of the company said, "MAPS is a protocol simulation and conformance test tool that can be applied to a variety of protocols such as MGCP, SIP, MEGACO, ISUP, ISDN, GSM, and others. He added, "The application is scripted and includes various real-time calling scenarios, traffic generation, test plans, test procedures, and test cases for comprehensive testing of protocols".
Mr.Kulkarni, further added, "MAPS MGCP protocol simulation and conformance testing application is designed to test Media Gateways (MG) and Media Gateway Controllers (MGC). It supports conformance test cases and call flow scenarios for MGCP entities in Voice over IP networks. The testing tool provides a MGCP test library that includes test functions to generate MGCP messages, edit messages, simulate a variety of call flows, and control scenarios. "Message sequences" are generated through scripts".
He added, "Some of the important features of the protocol are: Simulates Media Gateway Controller (MGC) and Media Gateway (MG), Generates and processes MGCP valid and invalid messages, Supports fully integrated, complete test environment for MGCP, Supports all the MGCP commands such as CRCX, NTFY, MDCX, RQNT, AUEP, AUCX, DLCX, EPCF, and RSIP, supports automated call generation using scripts, provides protocol trace with full message decoding, custom trace, and graphical ladder diagrams of call flow with time stamp while simulation is running, and Interactive GUI to view status, results, call information, total number of iterations and number of completed iterations".
Brief description of MAPS - SIP and MEGACO testing
MAPS™ SIP is designed to test SIP proxy servers, Redirect servers, Registrars and user agents such as SIP phones. Test cases include call flow scenarios for multimedia call session setup and control over IP networks.
The MAPS™ SIP Conformance Suite is designed with 300+ test cases, as per SIP specification of ETSI TS 102 027-2 document
The application gives the users unlimited ability to edit SIP messages and control scenarios (message sequences). "Message sequences" are generated through scripts. MAPS can also be used as a Bulk call generator, which generates and receives SIP calls up to 100,000 calls per system.
MAPS™ MEGACO is designed for MEGACO testing and provides a MEGACO test library capable of testing Media Gateways (MG) and Media Gateway Controllers (MGC). The test library includes test functions to generate MEGACO messages, edit messages, simulates a variety of call flows, and control scenarios. "Message sequences" are generated through scripts.
The MAPS™ MEGACO Conformance Suite is designed with 250+ test cases, as per specification of ETSI TS 102 374-2 document. The test suite includes in-built scripts to process MEGACO valid and in-valid behaviors. MAPS-MEGACO tool also simulates various Media Gateways call scenarios such as Analog Gateways and Trunking Gateways.
About GL Communications Inc
Founded in 1986, GL Communications Inc. is a leading supplier of test, monitoring, and analysis equipment for TDM, Wireless, IP and VoIP networks. Unlike conventional test equipment, GL's test platforms provide visualization, capture, storage, and convenient features like portability, remotability, and scripting.
GL's TDM Analysis & Emulation line of products includes T1, E1, T3, E3, OC-3, STM-1, analog four-wire, and analog two-wire interface cards, external portable pods, and complete system solutions. Capabilities include voiceband traffic analysis and emulation across all traffic types (voice, digits, tones, fax, modem), all protocols (ISDN, SS7, GR-303, Frame Relay, HDLC, V5.X, ATM, GSM, GPRS, etc.), and with capacities up to thousands of channels.
GL's VoIP and IP products generate / analyze thousands of calls / traffic simultaneously with traffic types such as frames, packets, voice files, digits, video, tones, noise, and fax using G.711, G.729, AMR, EVRC, GSM and a range of other codecs. Additional features include visual analysis, real-time listening, and recording. The product line also includes Ethernet / IP Testing capability that simulates and checks frame transport and throughput parameters of Ethernet and IP networks, including delay, errors and other impairments.
GL's Voice Quality Testing (VQT) product line complements all of GL's products. Using ITU-standard algorithms (PAMS, PSQM, and PESQ), GL's VQT provides a widely excepted solution across the telecom industry. Voice Quality Testing across multiple networks (T1, E1, T3, E3, OC-3, VoIP, Wireless, and Landline) are all available.
GL's Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA and UMTS networks. Connections can be made to any wireless phone with automated call control, GPS mapping and real-time signal measurements.
GL's Echo Canceller testing solutions provide the broadest range of simulation and analysis, including compliance testing per G.168 and G.160 across TDM, IP, VoIP and Wireless networks. GL's wirelss VQT solutions help assessing impairments to voice quality such as poor mobile phone quality, voice compression and decompression algorithms, delay, loss and gain in speech levels, noise, acoustic and landline echo, and other distortions are easily assessed and accurately measured.
GL's Handheld data testers can test a wide variety of communications facilities and equipment including T1, fractional T1, E1, fractional E1, T3 and E3 modems, multiplexers, CSU, DSUs, T1 CSUs, DTUs, NTUs and TIUs and more. The testers provide convenience, economy, and portability for almost any interface, including RS232, RS-422, RS-530, X.21, T1, E1, T3, E3, and many others.
GL's Network Surveillance and Monitoring products include Probes for TDM, IP, VoIP, ATM, and Wireless networks. An open standards based approach provides a scalable, feature rich, real-time access to network intelligence. Centralized or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based monitoring systems.
