Question about extending SIPp to send RTCP packets

[alishir]

Hi,
I want to run some integration tests for a signaling server and media engine using SIPp. I need to extend SIPp with some custom keywords such as <send_receiver_report>, <send_sender_report>, <recv_sender_report>, etc., to send and receive RTCP packets. With this feature, I can test that both my signaling server and media engine behave correctly during calls.
Could you please guide me on how to implement such a feature?

I just ran into this code last week. You can create a plugin for implementing custom keywords. See https://github.com/SIPp/sipp/blob/master/example/fortune.cpp.

Thanks a lot, @orgads.
I saw that example, but when I tried to build it I got some linker errors. Could you please share the build procedure? I used CMake to build SIPp from source.

Actually you'll need #820 and then build your plugin with the following command (assuming the build is in ../build):

g++ -shared -fPIC -I../include -I../build fortune.cpp -o fortune.so

And run sipp with -plugin $PWD/fortune.so.

Great, thanks a lot.

I built the sample plugin and used it successfully in a simple scenario. However, when I tried to get the media_port in the plugin, I couldn’t obtain the correct value. Do you know how I can access the call info? Many of the call class methods are protected, so I cannot invoke them from within the plugin source.
