Hi Bogdan,
indeed, I think I removed the append_branch() line by mistake when removing some debug lines I added to check function return code etc.
Thanks,
Takeshi

    Hi Takeshi,

    Aren't you missing the "seturi()" + "append_branch()" in the loop ??

        Hi,
        I'm testing latest
        commit b243666098be44226ade6a7df2b62851efcb5de8 of opensips-3.2.

        I tested adding branches to an INVITE for a fixed size list
        of AORs this way:

                    $var(aors) = "sip:us...@test1.com
        <mailto:sip%3aus...@test1.com>,sip:us...@test1.com
        <mailto:sip%3aus...@test1.com>,sip:us...@test1.com
        <mailto:sip%3aus...@test1.com>";

                    seturi($(var(aors){s.select,0,,}));

                    append_branch();
                    seturi($(var(aors){s.select,1,,}));

                    append_branch();
                    seturi($(var(aors){s.select,2,,}));

                    lookup("location", "r")

        The above works fine and all 3 destinations resolved by AOR
        lookup are called (max of contact per AOR).

        However, in case of a a list of unknown size, I tried to use
        a while loop like this:
                    $var(aors) = "sip:us...@test1.com
        <mailto:sip%3aus...@test1.com>,sip:us...@test1.com
        <mailto:sip%3aus...@test1.com>,sip:us...@test1.com
        <mailto:sip%3aus...@test1.com>";

                    $var(idx) = 0;
                    $var(aor) = $(var(aors){s.select,$var(idx),,});

                    while($var(aor) != null) {
                        seturi($var(aor));

                        $var(idx) = $var(idx) + 1;
                        $var(aor) = $(var(aors){s.select,$var(idx),,});
                    }

                    lookup("location", "r")

        But with the above, only the last destination (lookup of
        us...@test1.com <mailto:us...@test1.com>) is called.
        I confirmed this is not related to the lookup function
        because I tried with fixed destinations like this:

                    $var(aors) = "sip:user1@10.0.0.1:5072
        <http://sip:user1@10.0.0.1:5072/>,sip:user2@10.0.0.1:5074
        <http://sip:user2@10.0.0.1:5074/>,sip:user3@10.0.0.1:5076
        <http://sip:user3@10.0.0.1:5076/>";

                    $var(idx) = 0;
                    $var(aor) = $(var(aors){s.select,$var(idx),,});

                    while($var(aor) != null) {
                        seturi($var(aor));

                        $var(idx) = $var(idx) + 1;
                        $var(aor) = $(var(aors){s.select,$var(idx),,});
                    }

        and the same problem happens: only the last destination
        sip:user3@10.0.0.1:5076 <http://sip:user3@10.0.0.1:5076/> is
        called.

        So, is there a way to append a non-fixed number of branches
        to an INVITE?

        Regards,
        Takeshi


    Sorry, I think I did something wrong.
    I was able to make append_branch to work inside a while loop.
    So there is no problem.

    Takeshi
