[OpenSIPS-Users] next_gw still does append_branch in failure_route?

[Bogdan-Andrei Iancu]

Hi Jeff,

That is correct - I made a fix of LCR next_gw() function. It should work 
now.

Regarding DR questions: do_routing() accepts as param the routing group 
(as load_gw_from_grp()). For GW flags, there are the GW attributes (see 
http://www.opensips.org/html/docs/modules/devel/drouting.html#id272134)

Regards,
Bogdan
