Okay, I've performed some additional tests and this is what I've found:<br><b><br>codec</b> <b>max calls<br></b>speex (8kHz) 50<br>iLBC(8kHz) 50<br>PCMU(8kHz) 260(approx*)<br>GSM(8kHz) 150(approx*)<br>
speex(16kHz) 50<br>
G722(16kHz) 90(approx*)<br><br>* - couldn't trace till the total load of CPU 'cause RDP was timedout due to channel load. Calculated by trend.<br><br>Still I think Linux tests are necessary.<br><br>Cheers, Robert.<br>
