GL Communications Inc., a renowned leader in telecom testing solutions, recently made an announcement about their cutting-edge SIP protocol emulation and testing solutions. In today’s rapidly evolving telecom landscape, ensuring the seamless operation of SIP-based VoIP devices and networks is paramount. The innovative platform developed by GL Communications emulates all critical SIP elements and generates real-time SIP and RTP traffic for comprehensive testing.
Vijay Kulkarni, the CEO of GL Communications, emphasized the flexibility and power of the Message Automation & Protocol Simulation (MAPS™) software program. This versatile tool can emulate a wide range of telecommunications protocols, with a specialized application, MAPS™ SIP, dedicated to testing SIP-based communication systems. It effectively emulates key SIP elements such as User Agent Client (UAC), User Agent Server (UAS), Registrar, and Redirect servers.
MAPS™ SIP stands out for its ability to emulate complex SIP call flows and support high-volume call generation with real-time transmission of voice, video, fax, and messaging traffic. With comprehensive support for SIP over UDP, TCP, and TLS, it ensures thorough performance validation, resolution of interoperability issues, and confirmation of compliance with industry standards across VoIP and IP multimedia networks.
Key features of MAPS™ SIP include:
– Scalable Bulk Call Generation and Load Testing: Supporting up to 2,000 concurrent media calls at 250 calls per second, and 70,000 signaling-only calls at 750 calls per second, MAPS™ SIP can scale up to 160,000 calls at 800 calls per second with the MAPS™ RTP High Density appliance, making it ideal for testing network performance under heavy load.
– Flexible SIP Emulation for VoIP and Air Traffic Control Networks: MAPS™ SIP can emulate multiple SIP entities and generate diverse SIP messages without additional hardware, while also supporting EUROCAE ED-137C standards for accurate emulation of Air Traffic Control communication systems.
– SIP Testing for Gateway and Analog Telephone Adapter (ATA): Validating Gateway and ATA devices by testing connectivity, signaling behavior, and voice quality, including handling a variety of RTP traffic types such as voice, tones, digits, and fax.
– Remote Control and Integration: Supporting remote operation through a client-server Command Line Interface and APIs in Python or Java, enabling easy automation, integration with external systems, and distributed testing.
– Fax over IP Emulation and Analysis: Automating fax call generation and analysis for both T.30 and T.38 sessions to assess transmission quality, protocol handling, and system performance across SIP networks.
– Instant Messaging Support for NG9-1-1 over SIP: Integrating Message Session Relay Protocol (MSRP) to support instant messaging in NG9-1-1 networks, facilitating testing of IM-only sessions and mixed audio and messaging scenarios.
– Multimedia Call Emulation with Audio, Video, and Text Messaging: Emulating SIP calls with audio, video, and text messaging in a single session, with separate RTP streams for comprehensive end-to-end multimedia testing.
– Ensuring Protocol Compliance Across SIP Interfaces: Supporting standard SIP and variants like SIP-I, SIP IMS, and SIP MSRP to verify protocol conformance across diverse implementations.
– End-to-End IP Multimedia Subsystem (IMS) Testing for VoLTE, VoWiFi, and 5G Services: The MAPS™ SIP IMS Test Suite emulates core IMS nodes and supports SIP, RTP, and Diameter protocols, ideal for testing VoLTE, VoNR, and 5G services.
– SIP Protocol Conformance Testing with ETSI Support: With over 400 ETSI-based test cases, the MAPS™ SIP Conformance Suite ensures thorough validation of SIP implementations, configurable as a UAC to test UAS devices for various functions.
– Automated Interactive Voice Response (IVR) Testing: Automating IVR testing by sending DTMF tones or voice inputs for seamless navigation through IVR prompts and validation of response accuracy.
