The uac module (as well as other, like usrloc) do not apply q value
rules themselves. One has to use t_load_contacts()/t_next_contacts()
from tm for that, as you discovered already. If those functions are not
used, then parallel forking is done, ignoring the q values.
Cheers,
Daniel

I managed to work around the problem. I'd love to hear from anyone
who has gotten this module to work correctly.
I found two problems with the module:
(1) It is not supporting the q value correctly. It seems to be
sorting the q value in ascending sequence or is not sorting it at
all. I'm not sure which.
(2) Even though there were multiple different q values, the sip calls
were not serialized.
I was able to get around the problem with the following code that uses
the UAC Redirect module to gather the Contact Bindings and create the
branch. It does this part correctly. I then used the TM module to
handle the calls serially and to sort the bindings in descending
order. Here's the code:
modparam("tm", "contacts_avp", "tm_contacts");
modparam("tm", "contact_flows_avp", "tm_contact_flows");
# redirect with storing acc record
failure_route[REDIRECT_ACC] {
xlog("$var(loglevel)","In failure_route[REDIRECT_ACT]");
if(!t_check_status("3[0-9][0-9]")) {
xlog("$var(loglevel)","In failure_route[REDIRECT_ACT]
- NOT 3nn");
exit;
}
get_redirects("*:*", "redirect");
t_load_contacts();
t_next_contacts();
t_on_failure("serial");
t_relay();
}
failure_route["serial"]
{
xlog("$var(loglevel)","In failure_route serial");
if (!t_next_contacts()) {
exit;
}
t_on_failure("serial");
t_relay();
}

This is my first post so bear with me if I leave
something out.

I'm attempting to handle a 302 redirect being returned from another
sip switch. The 302 message contacts contains 6 redirect bindings
with a different q value for each. I'm using the UAC_redirect
module to handle the redirect. My problem is that it does not
serialize the sip calls. Instead it calls each in turn without
waiting for a response from the previous. I'm unable to configure
the redirect module to serialize the calls. What am I missing?
I've tried changing the get_redirects call to:
get_redirects("*:*", "redirect");
get_redirects("1:*", "redirect");
get_redirects("*:1", "redirect");
In debugging, I did notice that the q value seems to be
misinterpreted? The code that follows shows q values of
930,940,950 and 960. Is the module interpreting the decimal point
as a thousands separator?
The contact bindings:
"<sip:18452259999@192.168.10.125:5060>;q=0.990"
"<sip:18452259999@192.168.10.125:5060>;q=0.980"
"<sip:18452259999@192.168.10.125:5060>;q=0.970"
"<sip:18452259999@192.168.10.125:5060>;q=0.960"
"<sip:18452259999@192.168.10.125:5060>;q=0.950"
"<sip:18452259999@192.168.10.125:5060>;q=0.940"
"<sip:18452259999@192.168.10.125:5060>;q=0.930"
the on failure route:
failure_route[REDIRECT_ACC] {
xlog("$var(loglevel)","In failure_route[REDIRECT_ACT]");
if(!t_check_status("3[0-9][0-9]")) {
xlog("$var(loglevel)","In
failure_route[REDIRECT_ACT] - NOT 3nn");
exit;
}
get_redirects("*:*", "redirect");
xlog("$var(loglevel)","In failure_route contact branch
index:$branch(count)");
xlog("$var(loglevel)","In failure_route contact branch
q[0]:$(branch(q)[0])");
xlog("$var(loglevel)","In failure_route contact branch
q[1]:$(branch(q)[1])");
xlog("$var(loglevel)","In failure_route contact branch
q[2]:$(branch(q)[2])");
xlog("$var(loglevel)","In failure_route contact branch
q[3]:$(branch(q)[3])");
t_relay();
}
The log shows:
INFO: xlog:In failure_route contact branch index:7
INFO: xlog:In failure_route contact branch q[0]:930
INFO: xlog:In failure_route contact branch q[1]:940
INFO: xlog:In failure_route contact branch q[2]:950
INFO: xlog:In failure_route contact branch q[3]:960
Thanks in advance for any help.
