<p class="MsoNormal"><span lang="EN-US">I am trying to do some load testing on a freeswitch for transcoding from SILK to G711a. The question is: Is the limit for RTP sessions limited to CPU power or are there also limits on the freeswitch application and
can I tune freeswitch to do the job for 1500 sessions or more. <o:p></o:p></span></p>
