As VoIP and IMS networks grow more complex, advanced SIP testing solutions are critical to ensuring secure, reliable, and scalable communication services.Gaithersburg TodayGL Communications Inc., a global provider of voice testing solutions, has announced significant enhancements to its SIP testing platform, MAPS™. The upgraded platform enables high-load, secure, and automated generation of voice, video, fax, and messaging services across IP and IMS networks. MAPS™ SIP emulates a range of SIP entities, supporting comprehensive protocol conformance, interoperability validation, and performance testing across IP-based communication networks.
Why it matters
As VoIP and IMS networks evolve toward large-scale, multi-vendor architectures supporting secure real-time communications, validating signaling accuracy, media quality, and session reliability under realistic traffic conditions has become critical. Structured SIP testing enables service providers and equipment manufacturers to ensure interoperability, scalability, and deployment readiness across complex communication infrastructures.
The details
The enhanced MAPS™ SIP platform enables high-capacity RTP validation supporting up to 160,000 concurrent voice calls at 500 calls per second, along with seamless T.38 to T.30 fallback support for accurate fax interoperability testing. The solution also introduces automated call transfer capabilities using CSV-based profiles, enabling flexible execution of large-scale call scenarios for stress and regression testing. Security enhancements include support for 4096-bit TLS key length and improved cipher suite negotiation during TLS handshake, enabling validation of secure SIP communication workflows across enterprise and carrier-grade environments. Expanded Python API capabilities allow users to retrieve call statistics based on dialog types, reset statistics dynamically during load testing, and integrate automation workflows across Windows, Linux and macOS platforms.
