Once we tried to call outbound call getting no audio in both side also FreeSWITCH passing my server local IP as RTP-IP  to gateway side,


===========================
2017/06/29 12:57:06.579360 128.22.54.32:5060 -> 88.22.45.123:5060
v=0
o=FreeSWITCH 123456456 1245210017 IN IP4 192.168.1.101
s=FreeSWITCH
c=IN IP4 192.168.1.101
t=0 0
m=audio 31010 RTP/AVP 0 101
a=rtpmap:0 PCMU/8000
a=rtpmap:101 telephone-event/8000
a=fmtp:101 0-16
a=ptime:20
==============

192.168.1.101 = Amazon EC2 server local IP

88.22.45.123 = Gateway provider.

Could you please help me on audio issue in local-ip selected as RTP_IP and passing to gateway side?
