PacketGen VoIP testing tool

GL Communications has enhanced its VoIP stress testing tool called PacketGen, a software based VoIP testing tool that features real-time VoIP bulk call generation (including SIP signalling & RTP generation), stress testing, and analysis of VoIP networks and equipment. The latest version, PacketGen 3.0 supports SIP call generation (individual calls as well as bulk calling) and RTP/RTCP traffic generation. With PacketGen you can send/receive voice files, user-defined digits and tones, as well as create noise impairment and real-time voice traffic. TMC Labs has tested their testing products over the years, including their flagship product, the (Digital Central Office Switch Simulator (DCOSS), which we reviewed here and here.

Using PacketGen, calls can also be made to IP phones and to Analog Telephone Adapters (ATAs). PacketGen can be used to test basic functionality and verify proper protocol implementation in SIP based equipment such as SIP phones, as well as Proxy Servers, SIP Registrar servers, as well as PSTN and Media Gateways. One of my favorite features is its integrated impairment functionality. You can generate automatic impairments over the RTP for any (or all) established calls. These impairments include latency (Fixed, Uniform, Nominal), packet loss (Periodic, Random, Burst with burst probability and burst size), and packet effects (Out of order, Duplicate Packets).

Here is a list of their new features:
