Woops. The documentation problem was my fault. I was basing that on a
patched version of asterisk that jumped to another priority on FastAGI
failure. I'll update the wiki.

No, the information is wrong. You need to make a small mod to
res/res_agi.c
in order to trap this case. Look for the second occurrence of
LOCAL_USER_REMOVE, and add the lines just before it as show by this
patch extract (ignore the line numbers; I have other mods too):
@@ -2065,6 +2106,9 @@
close(fds[1]);
if (efd > -1)
close(efd);
+ } else {
+ pbx_builtin_setvar_helper(chan, "AGISTATUS", "NOTFOUND");
+ res = 0;
}
LOCAL_USER_REMOVE(u);
return res;
With this change, a refused connection will not hang up the channel, but
instead will set the AGISTATUS variable to "NOTFOUND".
Cheers
