[Freeswitch-users] No audio when calling in via SIP phone

Wed Jul 30 09:56:56 MSD 2014

Take a look in the ./conf/sip_profiles/external.xml file an in there
you'll find variables for the external rtp ip. I'm betting you haven't
set the external ip in the ./conf/vars.xml file. See here for more info:
