[OpenSIPS-Users] do_routing() sending several invites per call

[Magnus Burman]

Hi,

I'm moving from Opensips 1.4 to 1.6.1 currently and I'm getting some strange
behavior from droute. After it sends the INVITE, it resends it, and again,
for a total of 8 times, each time adding the opensips ip to record-route and
Via. Each invite gets its own record in radacct.

Anyone with an idea where I'm going wrong?

Below is the "relevant" part of my config:

route[1] {
    setflag(1);
    $avp(s:can_uri) = $ru;
    if (!t_relay()) {
        sl_reply_error();
    };
    exit;
}

route[10] {
# pre-processing with strips/prefixes etc
    ...
    if(do_routing("0")) {
        xlog("Regular routing");
        route(1);
        exit;
    }
    exit;
}

Below is the first INVITE sent out by Opensips. IP:s have been changed to
protect the innocent; they're all public, no NAT:
