I'm trying to setup custom aliases out of a sql db that will sometimes need to fork and need some help realizing how I can assign q values and process them correctly. I'm using kam 1.5.
Let's assume I query for our main support line and return 3 URIs from the db along with a separate column for the q.
Sip:us-support@mycomp.com q=1.0
Sip:uk-support@mycomp.com q=1.0
Sip:in-support@mycomp.com q=0.90
Based on the values I'd want to parallel fork on the first two to send this to my UK and US support line, if that fails cancel the first two branches and route to India. Just to see if I was on the right track I tried adding them as branches using $br, which from what I understand is the only way to add branches from avps/variables. I added them by appending ;q=1.0 on the end of the URI like you would see in a Contact header but I don't think that's valid. Calls to $(branch(q) return <null> so it obviously doesn't take.
If I were to just fork sequentially I could just load them into avps and call it in a failure route, but how do I handle a combination of the two? Am I wrong in trying to specify the q along with the URI?
I noticed serialize_branches was removed in 1.4, which is what I use in production today in 1.3 - do I need to use the replacements in TM to order them and add the branches?
Thanks in advance.

serialize_branches is replaced in 1.5 by tm functions t_load_contacts()/t_next_contacts(). you call t_load_contacts() after you have your uris (including their q values) in the destination set.
i don't use alias db and thus don't know about that.

I guess that's the part where I'm getting stuck. How do I go about adding my URIs with the proper q values to the dset? I'm not using alias_db, just sqlops with a custom statement that returns the URI/Q as columns.

have you tried append_branch with q value, something like this:
append_branch("sip:foo@bar;q=0.5");
if that does not work and no-one else on the mailing list has a better suggestion, open a new feature request on sr tracker.
i myself get q values into destination set using lookup or enum_query function.
-- juha
This works
append_branch("sip:3800@example.com", "0.90");
My next issue is that append_branch doesn't accept avps or pv as input parameters. Does anyone know the syntax (if there is one) to duplicate the above statement using assignments to $br?
I've tried a few combinations of assigning ;q=0.90 onto the end of the URI without success. If possible I'd prefer not to use the hack of modifying the ruri back and forth.

accodring to doc it should be also possible to assign directly, e.g.: uri in $avp(firsturi) and Q in $avp(firstq):
$br = $avp(firsturi) + ";q=" + $avp(firstq);

In the 1.5 code it doesn't look like it's possible to assign the q via pv assignment. The pv_set_branch function calls append_branch with Q_UNSPECIFIED.
if (append_branch( msg, &val->rs, 0, 0, Q_UNSPECIFIED, 0, msg->force_send_socket)!=1 )
Thanks for the help.
