All-
On a reasonably fast server, say quad-core, what is the approx maximum number of G711 IP calls when using Kamailio and rtpproxy? What if rtpproxy runs on a second server?
No echo can, no packet concealment, etc... just G711.

I'm told the number is over 1,000, but it is difficult to say how much over.

Taking into account that rtpproxy/mediaproxy only does RTP forwarding ... it's more a matter of how do you tune up your networking part (network card hardware, switch hardware, network tunning, etc.) and how many bandwitdh do you have available.
Also .. rtpproxy doesn't do anything with echo cancelation, or packet concealment ... that's a UAC/UAS task, not a proxy one.

I thought rtpproxy was pure userspace, not using kernel forwarding?

You are wright, so Context Switching should be taked into account also ... :-) ... so less stream forwarding cappacity.

Ok.

Yes agree. But in our case we modify rtpproxy to "re-route" UDP/RTP packets to a DSP PCIe card, which can provide additional capability, including transcoding. So I'm trying to establish a reasonable "base line" for max channel cap -- we would not want the DSP card to reduce the base line.
