What are you using - rtpproxy, mediaproxy etc? There is an experimental patch for advertised_address support in rtpproxy on the internet, but I've never had a chance to try it out. You may want to try spce-v2.2, which comes with mediaproxy-ng supporting the advertised_address out of the box: http://www.sipwise.com/news/announcements/spce-v2_2-release/

will kamailio as proxy behind nat and UACs behind another nat work?
port forward sip and rtp done in the router.
UACs register successfully but no audio.
advertised_address = public_ip advertised_port = sip
both define after the line of listen=public_ip
please advice.
thanks.
