We used this for our systems. http://startrinity.com/VoIP/SipTester/SipTester.aspx Adam From: VoiceOps [mailto:voiceops-bounces at voiceops.org] On Behalf Of Victor Breen Sent: Monday, August 25, 2014 6:14 PM To: voiceops at voiceops.org Subject: [VoiceOps] Need to stress test our SBCs I am looking for a way to generate some artificial load through our SBCs to simulate a daytime "busy hour" during late-night maintenance windows. I'm hoping to get audio quality measurements on both media legs, per test call, so I can validate that whatever changes were made during late hours will not manifest into issues for actual customer call traffic during peak times. I've heard of expensive hardware that can potentially do this (call hammer?), but I'm not aware of any "cloud-based" solutions. Does anyone know of a good "load testing as a service" out there that works well? What tools would you all recommend for this? -- Victor Breen, VoIP Systems Administrator Impulse Advanced Communications (805) 456-5800
