Can you specify which codec and number of concurrent channels (capacity) ? For older non-complex codecs (G726, GSM, etc) capacity won't make a
difference, for not-as-old codecs (G729, iLBC, AMR-NB) it will make some difference, and for more recent complex codecs (AMR-WB, Opus, EVS) it will
be significant issue. Also, rtpengine is using ffmpeg for codecs; freeswitch and asterisk run codecs included in their core source (also they have
ways for other resources on the network to run codecs).
