Not fixed length. Well it maybe fixed per technology. (Zap vs. SIP...)
I ended up just writing an AGI script.
extensions.conf:
; Now we dial!!!!
exten => 8901,6,AGI(strip-sess,DIALCHANS)
exten => 8901,7,Macro(stdexten,8901,${DIALCHANS})

#! /usr/bin/perl
$|=1;
$variable = shift;
while ($line = <STDIN>,$line =~ /[^ \n\r]/) { }
print STDOUT "GET VARIABLE $variable\n";
$response = <STDIN>;
$response =~ /^\d+ +result=(\d+) +\((.*)\)\s*$/;
$response = $1;
$data = $2;
if ($response == 1) {
$data = join("&",map {$_ =~ s/\-\w+$//;$_;} split(/&/,$data));
print STDOUT "SET VARIABLE $variable \"$data\"\n";
$response = <STDIN>;
}
exit(0);
