Running 1.2.14
When I call a FastAGI script such as this script for an incoming call:
[calldirect]
exten=>s,1,Answer()
exten=>s,2,AGI(agi://192.168.1.175/calldirect?check&${CALLERID(num)})
exten=>s,3,Goto(check_time,s,1)
and the FastAGI server is not running (Asterisk gets "connection
refused" TCP error), Asterisk just terminates the call like so:
May 17 12:58:00 WARNING[10154]: res_agi.c:210 launch_netscript: Connect
to 'agi://192.168.1.175/calldirect?check&NNNNNNNNNN' failed: Connection
refused
== Spawn extension (remove_caller, s, 2) exited non-zero on
'SIP/datatrak-0978b670'
The text of the relevant wiki article
(http://www.voip-info.org/wiki-Asterisk+FastAGI) infers that execution
should roll through to the next executable line in the context where it
was called in the case of an error in executing the FastAGI:
"Asterisk 1.2
Under Asterisk 1.2, if a request to a FastAGI service failed for any
reason, there was no way to determine this from the dialplan. The
recommended action is to set a channel variable before calling the
FastAGI, setting that variable to a known value within the FastAGI, and
then checking that variable once the AGI has returned..."
Is there a setting/var that I am missing?
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
Tony
Nice. Thanks, Tony.
Has this patched been accepted/committed in subsequent releases such as
a 1.2.17?
Thanks again,
Lee
