As also detailed in the other ticket, as well as in the documentation,
the engage_rtp_proxy() function has an undefined behavior when using in
a bridged scenario. Therefore I recommend you to use the
rtpproxy_offer/answer() functions.

For engage_rtpproxy there are two flags that are used i.e. i for LAN
interface and E for WAN interface. you can use these two flags to
specify your direction of bridging. e.g. ie for LAN to WAN bridging and
ei for WAN to LAN bridging. Meanwhile look at this documentation for
detailed flag usage.

Hi all,
i have an OpenSIPS server with two interface, PUBLIC (xxx) and PRIVATE
(172.20.1.2). The PRIVATE interface works inside a LAN dedicated to
VoIP, with a MediaServer (172.20.1.5) and a Patton Gateway for PSTN
(172.20.1.4).
Users phone's can register on both interface and i use RTPProxy (in
bridging mode) to ensure that both side can talk togheter.
But something don't work as expected....
Here's my OpenSIPS routing logic:

setflag(3); # ... even if the
transaction fails
} else if (is_method("INVITE")) {
# even if in most of the cases is
useless, do RR for
# re-INVITEs alos, as some buggy
clients do change route set
# during the dialog.
record_route();
}
# route it out to whatever destination was
set by loose_route()
# in $du (destination URI).
route(1);

/* uncomment the following lines if you
want to enable presence */

===========================================
and this is the RTPProxy config:
===========================================
CONTROL_SOCK=udp:127.0.0.1:12221 <http://127.0.0.1:12221>
# Additional options that are passed to the daemon.
EXTRA_OPTS="-l [external IP]/172.20.1.2 <http://172.20.1.2>"

Anybody can help me ?
