By doing "$(branch(q)[1]) = "0.1";" I was trying to write into an non existent branch since 1 is actually the second branch because the main branch ($ru) is not counted.

$(branch(q)[0]) = "0.1" // is the 1st.

$(branch(q)[1]) = "0.1" // is the 2nd.

Regards.

I can't set any of the attributes values using the assignment syntax. Everytime I do:

$(branch(q)[1]) = "0.1";
I get

ERROR: <core> [lvalue.c:354]: setting pvar failed.

This is true for all attributes, nut just for "q".

Am I doing something wrong? I'm using Kamailio 3.2.3.

Regards.

Looks like km_append_branch() doesn't have all of the signatures that the original append_branch() has. I can't add q values for serial/parallel forking with km_append_branch().

What signature are you looking for?

The latter is the one I'm looking for, but with the possibility of using pseudovars.

append_branch() overloads:

- append_branch();

- append_branch("sip:a@abc.com");

- append_branch("sip:a@abc.com", "0.1");

I am considering adding the second parameter to km_append_branch() for backward compatibility reasons.

Alternative is to use $branch(...) variable to set the q after you called append branch:

http://www.kamailio.org/wiki/cookbooks/3.3.x/pseudovariables#branch_attributes

Q has to be set via integer value, with range from 0 to 100 (0.1 would be 10).

Also, apparently there's no way of setting the RURI by calling a function that does that.

What do you mean here? I don't understand.

I'm was talking about setting the request-uri from a PV.

For example: seturi("$var(my_uri)");

But it works using assignation.

$ru = $var(my_uri);

The core functions were added before the existence of cfg variables, they take only static strings as parameters. The way to do it is via assignments.

I guess I'll have to do it using assignation on $ru pseudovariable and writing a route to manage the serial forking I need.

Thanks.

Hello,

Hello guys,

Why I can only append_branch() a SIP URI as a literal constant string? Why not from a pseudovariable? It's the same for most of the core functions.

My intention is to do something like this:

append_branch("$cnx3a(route1)");
t_relay();

where cnx3a is a variable containing the SIP URIs.

The only "fix" I have found for this is by doing it as follows:

$ru = $cnx3a(route1);
append_branch();
t_relay();

Is there any other (and more elegant) way?

you can use km_append_branch:
