Hello,

We are running Kamailio 1.5.

I'm trying to use the forward() function with a variable like this:

    forward($shv(voip1-edge1));

That fails to parse.

I then tried this, which I thought would fail:

    forward("$shv(voip1-edge1)");

That parsed correctly, but it then failed to resolve the domain '$shv(voip1-edge1)' as expected. Why can this function not use variables?

I tried to make a workaround by doing this:

    $du=$ru;
    $dd=$shv(voip1-edge1);
    forward();

That also failed. Why is $du writable but $dd is not?

I then made a fourth attempt, which seems to work:

    $du="sip:" + $shv(voip1-edge1);
    forward();

indeed, the last version is the one that works.

forward() does not take dynamic parameters, only static string values. $dd is not writable because is just part of $du which you can set like you did. $du refers to outbound proxy address (destination uri) and there matters only host, port and transport, all the other attributes in $du have no relevance.

Cheers,
Daniel
