Hi Varun, I wrote a signaling and media gateway running on Windows using PJSIP. I used the lower layer APIs you mention but did not use the bridge. I directly accessed the RTP, and passed it manually between the ports. I was able to run 256 simultaneous calls on a 3 GHz dual core processor with 4G RAM. I did most of my testing on VMs and still had good call quality and the systems was still approx 50% idle. I made real calls through the system while load tests were running and actually listened to the audio. I was using PJSIP 1.0 (or maybe 1.1). For directly accessing the RTP, see pjsip-apps/src/samples/siprtp.c good luck, Joel On Fri, Sep 16, 2011 at 10:56 AM, varun pratapsingh <varunps2003 at gmail.com> wrote: > Hi Arie, > > Thanks for your reply. > > But don't you think when you had 500 simultaneous calls and 500 RTP streams > then your call qualities were bad.
