Hi Andrew, I just use git... so not sure on the rpm stuff. However I believe 4.2 is to be released as stable branch tomorrow (see other recent thread by Daniel) so the packages probably aren't far behind.

The main reasons I see for using the 4.2 branch are: 1) its going to be stable release very soon 2) the options on rtpengine have been refactored ... makes sense to develop on the new version so that you can move from development to production without amending your kamailio.cfg 3) rtpengine seems to be getting quite alot of rapid progress at the moment and gaining stability and features ... I'd rather be on the latest version.

Having said all that the logic in the kamailio.cfg for version 4.1 is the same and should work for you if you want to work from the current stable packages.

Hi Andrew
There is a condition in the NATMANAGE route which tests whether or
not to apply rtpproxy_manage() :

    if (!(isflagset(FLT_NATS) || isbflagset(FLB_NATB)))
    		return;

One way to force this is to make sure that FLT_NATS is always set.
That can be done in the NATDETECT route by moving
setflag(FLT_NATS) outside of the if(nat_uac_test) condition and
putting it just before the return statement, so the flag is always
set.

Another way would be to remove or comment out the if
"!(isflagset(FLT_NATS) || isbflagset(FLB_NATB))) return;" line
from NATMANAGE so that the the rtp_manage() is always called.

It might be worth your while upgrading to the 4.2 branch which has
renamed the rtpproxy-ng module to rtpengine and made the options
in the call to rtpengine_manage() more readable.

Depending on why you always want to run the rtp proxy ... you
might also want to set :

     rtpengine_manage(replace-session-sonnection replace-origin ICE=force-relay)

to ensure that media always goes through your media proxy and no
other connections are negotiated between the endpoints.

hi,

kamailio 4.1.5 is used with rtpengine, whose older counterpart is
rtpproxy-ng. I made some changes based on the default
configuration files(i.e. kamailio.cfg), so that rtpproxy-ng
module is enabled. Kamailio.cfg has been uploaded. In
kamailio.cfg, there is one route block related to rtpproxy, i.e.
route[NATMANAGE], where rtpproxy_manage("co") is called.
Sometimes, rtpproxy-ng can insert new ip:port candidates in SDP.
But in some case, rtpproxy-ng doesn't rewrite SDP, so rtpengine
doesn't relay rtp packets at all.

How to setup kamailio.cfg, so that rtpproxy-ng moudle can always
rewritten new ip:port candidates, and rtpengine always relays rtp
packets?

Looking foreward to your reply. Thanks!

B.R.

Andrew
