SIP RTP Protocol Simulation using MAPS­™

Featured Product from GL Communications, Inc.

SIP RTP Protocol Simulation using MAPS­™-Image

MAPS™ can 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.

MAPS™ SIP supports transmission and detection of various RTP traffic such as, digits, voice file, single tone, dual tones, IVR, FAX*, and Video*. With regular RTP traffic, the maximum Simultaneous Calls up to 2500, and Calls per Second up to 250 is achievable. Almost all industry standard voice codec supported.

High volume of calls generation with traffic for load testing network is possible using MAPS™ RTP HD (PKS109) network appliance.

Signaling Features

  • Generates and processes SIP valid and invalid messages
  • Supports complete customization of SIP headers, call flow, and messages
  • Supports complete customization of scripts and parameters in the profiles
  • 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 64-bit version to enhance signaling performance
  • Supports conference call, blind call transfer, hold, auto call rejection, and silence packets generation
  • Ability to send "reliable provisional responses" and start early media actions
  • Supports VoIP implementation as per ED-137B of EUROCAE standard
  • Ability to implement IP Spoofing for any network like Class C, Class B etc

Traffic Features

  • 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 different traffic options across simultaneous calls
  • Supports almost all industry standard codec types - G.711 (mu-Law and A-Law), G.722, G.729, G.726, GSM, AMR, AMR -WB, EVRC, EVS, OPUS, SMV, iLBC, SPEEX, and more. *AMR, EVRC, EVS, and OPUS variants require additional licenses.
