So, now just to close on this question. When gmail client / gtalk client is not in same LAN I should give param name="candidate-acl" value="wan.auto" param name="local-network-acl" value="localnet.auto" param name="ext-rtp-ip" value="$${external_rtp_ip}" Where external_rtp_ip is configured in vars.xml as stun:stun.freeswitch.org However, in some instances of the call there was no audio both side. ICE negotiation was not successful. But, some other time (When i Logout from both sides and login again), call was again with perfect audio. Need to check this instability! ------ But if gmail client is in same LAN then remove above three lines and provide param name="candidate-acl" value="rfc1918.auto" - With this set-up, calls always work perfectly :) NOTE: This is everything for inbound calls. I havent still tried out-bound calls. -- View this message in context: http://freeswitch-users.2379917.n2.nabble.com/Help-on-freeswitch-gtalk-sip-c...
