Hi Have you tried using the "a" mode of force_rtp_proxy? This will disable symmetric RTP which it seems is broken by your E72. Leo On 12 May 2013, at 12:39, hiro <23h...@gmail.com> wrote: > On 5/12/13, Leo Brown wrote: >> Hi >> >> I don't know the e72, but if you do a `tcpdump -A -s0 port 50

Hi I don't know the e72, but if you do a `tcpdump -A -s0 port 5060` we can see the SDP data to determine the issue RTP should be sent to the address defined in SDP unless a symmetric RTP setup is used for auto NAT traversal- but I believe only Asterisk provides this, not rtpproxy. Leo Leo Brown
