The a= line should be added only when force_rtp_proxy() is used,
which should happen when is a call that involves NAT, unless you
call that function for all calls.<br>
<br>
Use ngrep on kamailio server to watch traffic on port 5060 and check
if the sdp for INVITE and 200 OK have the proper IP addresses --
they should be rtpproxy ip address when invoking force_rtp_proxy().<br>

<div>I am using PJSIP as my UA, kamailio 3.1.5 , rtp proxy 1.2.1
as intermediate proxy for signalling and media. In kamailio
config, I have enabled WITH_NAT.</div>
<div>On call setup, only one way audio is there. When I looked at
SIP messages, the only additional stuff I can see a=nortpproxy
and nat=yes in recpord route.</div>
<div> </div>
<div>Without kamailio as intermediate proxy, audio is good both
way. </div>
<div> </div>
<div>So I feel, when I bring up kamailio as intermediate proxy I
am doing some mistake configuration wise either at PJSIP UA or
in Kamailio.</div>

<div>Has anybody faced this issue previously.</div>
<div>If so please share how can we fix this issue.</div>
<div> </div>
<div>Thanks in advance</div>
