I'm troubleshooting Tone detection in Freeswitch installed in AWS (Debian) I have 2 servers one works the other doesn't: *FreeSWITCH (Version 1.7.0 -928-db61f4d 64bit)* DigitalOcean WORKS http://pastebin.com/bPx4xGCP *FreeSWITCH (Version 1.6.9 -16-d574870 64bit)* is ready AWS FAILS http://pastebin.com/ktnFYJ05 *Troubleshooting* Seems to be that Freeswitch in AWS EC2 because of NAT is not able to get the RTP from remote side. When I do a packet capture I don't get any RTP from remote end and in initial SIP SDP from Freeswitch I do see local IP address from AWS even though ext-X params are configured. 1. One instance is installed in AWS, the other one in DigitalOcean, 2. I'm originating my calls using ESL and my Gateway: *originate {ignore_early_media=true}sofia/gateway/asterisk/+14171111111 handle_calls* 3. I already configured* ext-rtp-ip and ext-sip-ip* fields in external.xml <param name="ext-rtp-ip" value="$${external_rtp_ip}"/> <param name="ext-sip-ip" value="$${external_sip_ip}"/> https://www.twilio.com/resources/images/docs/Twilio-Freeswitch.pdf Any ideas? *Logs* sofia status gateway asterisk ================================================================================================= Name asterisk Profile external Scheme Digest Realm 192.241.203.21:5090 Username FreeSWITCH Password no
