Sorry, I can not send you log, but You can reproduce it with script below

route {
    xlog("L_ERR", "main route $rm $cs\n");
    rewriteuri("sip:my ip:wrong port");
    t_on_failure("1");
    if (!t_relay())
	sl_reply_error();
}

failure_route[1] {
    xlog("L_ERR", "failure_route $rm $cs\n");
    append_branch("sip:my ip:another wrong port");
    t_relay();
}

With this script i got next output:

1: main route REGISTER 1
2: main route REGISTER 1
3: main route REGISTER 1
4: failure_route REGISTER 1
5: main route REGISTER 1

// "408 Request Timeout" was returned

6: main route REGISTER 1

// "477 Unfortunately error on sending to next hop occurred (477/TM)" was returned
