Well, there is one way to do that, simply shorten the port range. A typical audio call with two way media consumes 4 ports (caller rtp + caller rtcp + callee rtp + callee rtcp), So if you want media relay to stop accepting calls beyond 500 concurrent calls just set port range to 2,000. For 501th call media relay will reject telling dispatcher that its out of available ports and dispatch will try another relay (if available) or reject call to opensips (if no other relay) and in turn opensips will reject call with response code 500.<br>

There is no software limit but rather available bandwidth that limits number of concurrent calls as far as media proxy is concerned. Theoretically a G711A/U call (with two way media) requires roughly 160 kbps bandwidth, which yields around 640 concurrent calls on 100 mbps connection. And if you have say iLBC or G729 call (with two way media) then should be able to handle around 5 times more. However this assumes that you have dedicated / consistant bandwidth which is only used by RTP traffic, which almost never happens in practice, since there are always some other services running using network.<div>

</div>There is no such a setting :-)<br>
