Hi Alex,
We already had this line in our kamailio.cfg:
modparam( "nathelper|registrar", "received_avp",
"$avp(RECEIVED)" )
We do need to change the received parameter conditionally depending on
the
user agent, and the following seems to work:
if ( $ua =~ "ewb2bua" ) {
avp_subst( "$avp(RECEIVED)", "/(.*);transport=TLS/\1/i" );
}
Can you see any issues with this?
Thank you!
