[Users] Question about voip-info.org's OpenSER/RTPProxy configuration example

[Jeremie Le Hen]

Hi list,

I was exploring the example configuration file in the following URL:
http://voip-info.org/wiki/view/OpenSER+And+RTPProxy

The following block bewilders me:
% failure_route[1] {
% 	if (isflagset(6) || isflagset(5)) {
% 		unforce_rtp_proxy();
% 	}
% }

How a flag happens to be turned on there ?  6 is the registrar's nat_flag
but no lookup() is performed.  Furthermore, the tm module doesn't even
depend on the registrar module.  Flag 5 is set in route[2] which is
obviously not called from failure_route[1].  Is there some black magic
around here ?

Thank you.
Regards,
