Hi,

OpenSIPS all the time adds is Route as a loose route, so for its ownRoute, when doing loose_route() will act as loose router all the time.Nevertheless, when checking the next hop, OpenSIPS can handle both astrict or loose router (as next hop).


But once again, opensips itself does only loose routing for its Routes.

Hi Bogdan,

i see in the opensips Docs the definition of loose_route() function:

" The function performs routing of SIP requests which contain a routeset. The name is a little bit confusing, as *this function also routesrequests which are in the “strict router” format. "*

so Does this function do the strict routing also ? according to whichchapter in RFC this routing belong ?

    Hi,

    That is not true - OpenSIPS acts all the time as a loose router.
    The param you mentioned simply changes on how the "loose router"
    label should be advertised : (1) "lr" or (2) "lr=on" - but both do
    mean a loose router.

    Hi ,
    the statment *modparam("rr", "enable_full_lr", 1)*  in the script
    lets opensips uses lr=on instead of just ;lr to work as loose
    router, so it behaves as strict router where it should be loose
    router   in fail case, since it detects only ;lr in messages.

        As the next destination should be 6.6.6.6, some stupid questions:

        1) is 6.6.6.6 configured in domain module or as "alias" ?

        2) have you check to loopback interface ? maybe the ACK is
        spiraling
        over there.

        Also, try to reproduce the ACK case, but enable full debug in
        script for
        the loose_route() function:
             if (is_method=="ACK") setdebug(6);

        And post the output of opensips - this will give some clue on
        what it is
        doing.
