ProLab SIP Testing - Spirent

The ProLab Testing Suite encompasses a wide range of testing tools for several environments and includes the following add-ons:

Terminal Simulation

Performs advanced simulation by generating signaling and media. By generating calls, the ProLab Testing Suite performs a variety of tests, including protocol and stress tests. 

IMS Server Simulation

Can act as an IMS Server in order to simulate different network topologies and to simulate different entities on a VoIP network. Servers that can be simulated include: P-CSCF, I-CSCF and S-CSCF. 

Analysis & Report

The ProLab Test Results Analysis Solution offers an intuitive tool to automate testing and results analysis and flexible report generation that can be customized to specific requirements.

Voice Quality

ProLab is equipped with both MOS and PESQ (Perceptual Evaluation of Speech Quality) voice quality tools.

Video Quality

The Video Quality measurement uses different video metrics. It intrusively analyzes received video streams and perceptually scores relevant degradations on a 5-point MOS scale. Additional key performance indicators (KPIs) are output to allow experts to make a more detailed analysis. The video Quality add-on support reference 

ProLab Video Quality - Spirent


The ProLab SIP Testing Solution supports automated testing for both large-scale operations and small to medium-sizes needs. It uses an XML/SOAP interface for controlling the ProLab system and an intuitive Test Scheduler with a sophisticated scheduling for comprehensive automated test procedures.

The Session Initiation Protocol (SIP) is the dominant industry signaling protocol used for real-time communication applications such as voice over IP (VoIP) and Instant Messaging (IM). Based on ubiquitous and accepted Internet protocols such as SMTP and HTTP, SIP is text encoded and well suited for the Internet and other IP environments. SIP provides the mechanisms to implement a broad range of features, including call control services, next-generation service creation, interoperability with existing telephony systems, and mobility.

RFC 3261 (SIP)
RFC 3262 (Reliability of Provisional Responses in SIP)
RFC 3265 (SIP Specific Event Notification)
RFC 2327 (SDP)
RFC 2617 (HTTP Digest Scheme Authentication)
RFC 3515 (REFER)
RFC 3372 (SIP-T)
RFC 2833 (DTMF signaling above RTP packets)
RFC 2246 (TLS v1.0)
RFC 3546 (TLS Extensions)
RFC 4028 (Session Timer)
RFC 3263 (locating SIP Servers)


All Spirent products and solutions take into account interoperability issues between disparate networks, protocols and devices. The ProLab SIP has been thoroughly tested for full interoperability with other clients and servers.
