As per the documentation, $branch(name) provides access to "additional branches", not "main branch". If after lookup you have a single branch (AoR has a single Contact), it would explain why you get NULL.

Not, I tried $branch(uri) and I can't get it either. 

lookup() function seems to be returning true back, this is related config code:

lookup("location");
switch ($retcode) {
    case -1:
    sl_send_reply("404", "Not Found");
        exit;
    case -2:
        sl_send_reply("404", "Method not supported");
        exit;
    case -3:
        sl_send_reply("405", "Internal Error");
        exit;
};

xlog("Return Code|Branch Count|Branch URI: $retcode|$branch(count)|$branch(uri)\n");

and in the logs I'm getting this:
Return Code|Branch Count|Branch URI: 1|<null>|<null>

Hello,

can you get any other attribute from the variable?

At least the uri should be set.

Also, have you tested that lookup() was true?

Cheers,
Daniel

Hello,

As per documentation after lookup() function I have to get the number of branches from the main branch by using $branch(count) variable, but for some reason, I'm getting always only <null> value, can someone help me to understand what I'm doing wrong?

lookup();
xlog("Branch Count: $branch(count)\n");
