How to test SIP trunk capacity in UK?
We had some issues with our SIP provider in London recently. Needed to see how many concurrent calls the line can handle before it starts dropping quality. If you ever need something like this, you can look at just kill net. It is a simple tool that does the job without any complicated setup. I used it for a couple of hours and it gave me the data I needed to talk to my provider. It is quite cheap and works fine for basic stress testing.
