Why can't prefix() accept a pseudovariable argument, e.g.
prefix("$avp(S:the_prefix)");?
It is interpreted literally.
this is old function from core -- most of them do not take pseudo-variables as argument. You can use instead:
$rU = $avp(S:the_prefix) + $rU;
That's what I ended up doing. I was just wondering if there was some philosophical / design-related reason for it and you answered my question. :)
Nothing particularly, just that the function was not updated to take in consideration pseudo-variables. For a future version based on sip-router we look to a different approach to handle parameters that will allow kind of automatic conversion of pseudo-variables...
