Comparing Performance of Chan SIP and pjsip 

Since the Asterisk project launched the latest sip channel “chan_pjsip”, there were very few publications showing the performance gains or even losses of the new channel. In this presentation, we are going to use SIPP to measure the SIP performance of both channels for the latest versions of Asterisk. Below a list of topics to be presented. • Main differences between channels from practical perspective • Testing methodology and failure criteria • SIP registration performance • SIP performance for calls to the server (echo) • SIP performance for calls between UAC and UAS • Tips on how to increase SIP performance and registration performance
