[OpenSIPS-Users] UDP to TCP issue with Re-INVITE

[Mickael Hubert]

Hi David,
Yes I use it

if (nat_uac_test("3") && ($Ri == $var(publicip) || $Ri == $var(vpnip)))
{
xlog("L_INFO","$avp(startlog) -- Nated EP Detected\n");
if (force_rport())
{
xlog("L_INFO","$avp(startlog) -- RPORT parameter forced\n");
}
if (fix_nated_contact())
{
xlog("L_INFO","$avp(startlog) -- Nated $rm's Contact Fixed !\n");
}
if (fix_nated_sdp("10"))
{
xlog("L_INFO","$avp(startlog) -- Nated SDP Fixed for $rm\n");
}
}
