Help: Using ccRTP to handle mutiple RTPSessions

Hi All,

I am using ccRTP to generate RTP packets for multiple RTP sessions (pair of
ports for each session). I am little confused with the threading model to be
used here.

*. In ccRTP manual, it says a separate execution thread for each RTP session
handles the queues. so is that mean that for 10 sessions , 10 threads will
be running ? 
*. and also Is that mean that each RTPSession will have a saparate queues ?

Please correct me if i am wrong & can any body share there experience in
using the ccRTP to handle multiple sessions. 

Thanks in advance,
Irshad
