GL Announces Enhanced SIP Protocol Emulator

In a GL Communications’ Newsletter January edition providing information and insight into their latest enhanced MAPS™ SIP Protocol Emulator. The emulator will help a user to generate and receive SIP Signalling with traffic.

GL’s Message Automation & Protocol Simulation (MAPS™) designed for SIP testing can simulate User Agents (User Agent Client- UAC, User Agent Server-UAS), Proxy, Redirect, Registrar and Registrant servers. This test tool/traffic generator can be used to simulate any interface in a SIP network and perform protocol conformance testing (SIP protocol implementations).
It can also be used to simulate any interface of the VoIP network. Single MAPS™ instance can act as more than one SIP entity at a time and can generate any SIP message on wire in VoIP network and hence equipment needed to test are reduced. MAPS™ SIP supports UDP, TCP, TLS transport types. Secure Real-time Transport Protocol (or SRTP) traffic supported over TLS (Transport Layer Security) Transport and TLS Library (OpenSSL) uses a Certificate and Key.

Some of the Important Features

  • Generates and processes SIP valid and invalid messages
  • Supports complete customization of SIP headers, call flow, and messages
  • Each SIP message template facilitates customization of the protocol fields and access to the various protocol fields from the scripts.
  • Supports IPv4 /IPv6 and transport over UDP and TCP, and TLS for secure transport
  • Handles Retransmissions of messages with specific interval
  • Scripted call generation and call reception.
  • Supports conference (third-party added), attended call transfer, and call forwarding.
  • Supports transmission and detection of various RTP traffic such as, digits, voice file, single tone, dual tones, IVR, FAX, and Video in IP networks.
  • Supports almost all industry standard codec types – G.711 (mu-Law and A-Law), G.722, G.729, G.726, GSM, AMR, EVRC, SMV, iLBC, SPEEX, and more. *AMR and EVRC variants require additional licenses. Click here for comprehensive information on supported codecs.
  • Supports both RTP G.711 Pass Through Fax Simulation (PKS200) and T.38 Fax Simulation over UDPTL (PKS211) simulation over IP.
  • Test IVR, and Instant messaging features.
  • Transmit and receive pre-recorded video traces supporting video codecs like H.264, H.263, and VP8
  • With normal RTP Maximum Simultaneous Calls – 2500, and Calls per Second – 250 (in high end server machines). Without RTP (only signaling) Maximum Simultaneous Calls – 70,000, and Calls per Second – 750 (in high end server machines)
  • With MAPS™ HD RTP network appliance up to 20,000 endpoints per unit can be easily achieved (requires PKS109 and specialized hardware)
  • Capability to generate more than 500 simultaneous video calls on Core i7 systems
  • Enhanced  with 64bit RTP support
  • Support  for T.38 Fax Simulation
  • Support for TLS and SRTP
  • Enhanced to support Java and Python CLI API’s
