Applications

• Complete test lifecycle coverage: feature, negative, load, regression, interoperability and scalability testing
• Security testing capabilities such as protection against theft of service, SIP flood/DoS and rogue media
• Characterization of voice, video and DTMF impairment

IP-to-IP gateways such as session border controllers, H.248 border gateways, security gateways and firewalls, play a critical role in enabling and protecting the new generation of multimedia services, which are driving the deployment of VoIP and fixed mobile converged (IMS) networks.

VoIP and IMS IP-to-IP gateways support a number of core functions such as security against theft of service and malicious attacks using SIP flood/DoS and rogue media, per-session policing, QoS monitoring and reporting as well as secure access to services.

This IP-to-IP Gateway Test Suite focuses on testing these critical functions, which ensure the viability of VoIP and IMS services.
