capture:
Note: Open sip.conf and add the following line under [general] context
before continuing to the next steps.

Asterisk
by default tries to redirect the RTP media stream to go directly from the
caller to the callee. If this is set to “no” then the
entire RTP media stream will go through the Asterisk server. Setting it to “no”
is required if you want to control the traffic at the Asterisk server (This is
what we intend to do in the next steps).
