Dears, First sorry it you received the below content of this email with wrong subject

The issue we face with some of our sip peers complaint that we sent in our SDP contains two 'c='

o=- 1552491282093 1 IN IP4
s=Our Local Private Media Server.
c=IN IP4 ****
t=0 0.
m=audio 36356 RTP/AVP 8 0 101.
c=IN IP4 **Public.Interface.RTPPRoxy.**
a=rtcp:36357 IN IP4 Public.Interface.RTPPRoxy.
a=rtpmap:0 pcmu/8000.
a=rtpmap:101 telephone-event/8000.
a=rtpmap:8 pcma/8000.

I am using RTPProxy inside the script just like below
	rtpproxy_offer("nt60T60", "$avp(advertised_address)", "$avp(mediaSet)",)
	rtpproxy_answer("ocnt50T50", "{{ ips.opensips }}","$avp(mediaSet)" , ) ;

how could I hide private IPs in above SDP that reach our trunk side ?

Best regards ,
