Do you see (with ngrep or tcpdump) the INVITE being sent
out by opensips towards callee ?<br>

By 'call fails to connect', I meant the call does not
connect to the callee, ie. the callee's phone does not
ring after the INVITE (despite using TURN server). </p>

Hard to analyze a call based on the INVITE packet
only :). Still the SIP signaling does not show any
ALG interference (also not sure if the capture was
done before or after the ALG). Also, what you mean
by "call fails" ?no reply, negative reply , no
audio ?<br>
<br>

<div class="gmail_extra">Please check the
following SIP trace taken within a WiFi

INVITE request and using a non-standard port.
Could this be caused by SIP ALG, or some
unopened RTP port on the router?</div>
