Wireshark-dev: [Wireshark-dev] Question regarding RTCP protocol

Hi everyone, I have a question regarding RTCP protocol. I have to measure the jitter, packet loss and roundtrip delay for each call. I know that in the statistics menu in the RTP Stream Window I can read the Mean Jitter and Packet Loss per call, and if in the general window I filter the RTCP protocol I´m able to read the roundtrip delay per packet per call in the sender´s report.
 
My problem is that I can have a lot of calls between the same 2 elements, (between 2 IP´s addresses (A and B)), so in the RTP Stream  Window I can read a lot of calls between 2 IP´s source and destination (A and B). How can I relate the roundtrip calculation value in the general window when I filter wiht RTCP protocol with a specific call in the RTP Stream Window if the info I have is the IP address for the source and destination (A and B) and there are a lot of calls between them.
 
My question is how I can I know from which call is that RTCP sender report?
 
Is there a specific field in the RTCP packet where I can relate that report with a specific call? So I can know for each call between  2 elements the 3 parameters (jitter, packet loss and roundtrip delay)
 
Thanks for your time, looking forward for some help!
