Disable SIP ALG on your router. This is enabled by default in most routers. However, it is known to cause conflicts with external VoIP devices. For more information on how to disable SIP ALG, click here. Remember to reboot or restart your router after each troubleshooting step to make sure any changes made are applied correctly. Sergey was responsible for VoIP troubleshooting, so he created a tool to generate SIP calls, the tool finally was marketed as SIP Tester (his first commercial product). Beyond the SIP Tester there are many other products, part of them published on the website. Sergey worked as freelancer at upwork (former odesk) in 2010.2014.
SIPp is a free Open Source test tool / traffic generator for the SIP protocol. It includes a few basic SipStone user agent scenarios (UAC and UAS) and establishes and releases multiple calls with the INVITE and BYE methods. It can also reads custom XML scenario files describing from very simple to complex call flows. It features the dynamic display of statistics about running tests (call rate, round trip delay, and message statistics), periodic CSV statistics dumps, TCP and UDP over multiple sockets or multiplexed with retransmission management and dynamically adjustable call rates.
Other advanced features include support of IPv6, TLS, SCTP, SIP authentication, conditional scenarios, UDP retransmissions, error robustness (call timeout, protocol defense), call specific variable, Posix regular expression to extract and re-inject any protocol fields, custom actions (log, system command exec, call stop) on message receive, field injection from external CSV file to emulate live users.
SIPp can also send media (RTP) traffic through RTP echo and RTP / pcap replay. Media can be audio or video.
