If so, it’s possible, you just need two separate scenarios: One to send the INVITE and wait for the ANSWER, and another to (optionally) REGISTER and wait for the INVITE, then send the ANSWER. You can also use RTP Echo within SIPp to reflect any received media back to the far end, which is an easy way to pass audio without messing with recordings.</div><div><br class=""></div><blockquote type="cite" class=""><div class=""><div dir="ltr" class=""><div class=""><br class=""></div><div class="">BTW, when I try to install sippy_cup, I get an error:</div><div class=""><br class=""></div><div class=""><div class="">~/sipp-3.5.0$ sudo gem install sippy_cup</div><div class="">Fetching: network_interface-0.0.1.gem (100%)</div><div class="">Building native extensions.
