Make your AGI script fork itself; have the child process detach, and the 
parent process exit.  Then, the AGI call will return quickly to the dialplan; 
and meanwhile, the script can continue in the background at its own leisure.

Example code  (Perl)  follows:

#!/usr/bin/perl -w
use strict;
use Asterisk::AGI;

my $child_pid;

my $AGI = new Asterisk::AGI;
my %params = $AGI->ReadParse();


if ($child_pid = fork) {
    #  This is executed in the parent process
elsif (defined $child_pid) {
    #  This is executed in the child process
    close STDIN;
    close STDOUT;
    close STDERR;
    #  Now we are detached

    #  This is where we do the funky stuff

else {
    #  Oh, s#!t
    die "Could not fork: $!";
#  We should never, ever get here


Answers come *after* questions.
