GL Communications' PacketGen provides VoIP simulation for Session Initiation Protocol (SIP) and RTP traffic, with an additional option of supporting H.323 calls.  PacketGen is software-based SIP solution that is capable of residing on one or more Windows based PC containing a 10/100/1000 Ethernet Port.  Analysis of the received and terminated SIP or RTP traffic can also be provided on the same computer via GL's PacketScan software, allowing the user to quickly drill down into problematic calls.

Capabilities

• Manual and Bulk Call SIP, RTCP and RTP simulation.
• Support for SIP Supplementary Services.
  • Call Forwarding, Call Hold, Call transfer etc.
• Impairing Established Calls using Latency, packet Loss etc.
• Generates Call records and Statistics for SIP/RTP events and calls.
• E-Model based MOS and R-Factor.

Tests Performed

PacketGen is based on a distribution architecture, wherein SIP and RTP software cores can be modularly stacked, in one or many PCs to create a scalable high capacity test system.  All SIP functionality is provided including Register, Authentication, Transfer, Redirect, and more.  Also, using the software RTP, one can send/receive voice, DTMF/MF digits(both in band and out of band) and user-defined frequency tones.  An optional hardware RTP can support 120 real-time voice calls from real phones, or fax calls from fax machines, as well as supporting T.38 faxing.

Summary

GL's PacketGen VoIP Call Simulator is a powerful and cost effective tool to assess today's complex VoIP networks.  The scalable software-based solution offers users the chance to verify signalling and media traffic as well as link characteristics such as timing, delay, voice quality and echo.  The GL PacketGen offers the potential to change your PC into a powerful SIP simulator and allow you to quickly and efficiently test your VoIP network.
