It may not be you, I think the Festival driver is buggy. Specifically, I've found that the the way in which you pass the text to Festival matters. If I use the Festival () suntax then it won't work. If I use the wrong sort of quotation mark " instead of ' there are problems. Asterisk will consume vast amounts of processor resources.
However, if I specify the command in a way the Festival app likes then all is OK. Try variants like:
exten => 555,4,Festival,'mary had a little lamb'

Hello,
I have Asterisk running on a RH9 box; Everything seems to be working as it should, except for Festival. Every time that Festival is called from Asterisk, Asterisk silently shuts down. Festival doesn't give any error indication and Asterisk just plain dies without a peep.
Festival was installed per the Wiki, using source and patched with festival-1.4.3-diff; it works fine at the console. Asterisk is built from CVS and has been configured per the Wiki as well, including the test extension (555). I start Festival with the "festival_server" script, then start Asterisk.
(snippet from extensions.conf) exten => 555,1,Answer exten => 555,2,Festival(mary had a little lamb) exten => 555,3,Hangup
Here's what Asterisk says with -vvvvv, calling from SIP 81001 to 555: Asterisk Ready. -- Executing Answer("SIP/81001-e87b", "") in new stack -- Executing Festival("SIP/81001-e87b", "mary had a little lamb") in new stack == Parsing '/etc/asterisk/festival.conf': Found == Spawn extension (from-sip, 555, 2) exited non-zero on 'SIP/81001-e87b'
...at this point Asterisk is dead. No segfault, no error message.

I'm guessing the ouch comes from mpg123 being surprised that Asterisk is gone.
Debug info in syslog seems pretty unhelpful if I use -d: Jan 7 15:37:00 asterisk_pbx[5038]: Jan 7 15:37:00 DEBUG[1150495040]: File chan_sip.c, Line 4024 (check_user): Jan 7 15:37:00 asterisk_pbx[5038]: Jan 7 15:37:00 DEBUG[1150495040]: File chan_sip.c, Line 5098 (handle_request): Jan 7 15:37:00 asterisk_pbx[5038]: Jan 7 15:37:00 DEBUG[1150495040]: File chan_sip.c, Line 1002 (find_user): Jan 7 15:37:00 asterisk_pbx[5038]: Jan 7 15:37:00 DEBUG[1150495040]: File chan_sip.c, Line 3417 (build_route): Jan 7 15:37:00 asterisk_pbx[5038]: Jan 7 15:37:00 DEBUG[1234379840]: File app_festival.c, Line 304 (festival_exec): Jan 7 15:37:00 asterisk_pbx[5038]: Jan 7 15:37:00 DEBUG[1234379840]: File app_festival.c, Line 361 (festival_exec): Jan 7 15:37:00 asterisk_pbx[5038]: Jan 7 15:37:00 DEBUG[1234379840]: File app_festival.c, Line 363 (festival_exec): Jan 7 15:37:00 asterisk_pbx[5038]: Jan 7 15:37:00 DEBUG[1234379840]: File app_festival.c, Line 379 (festival_exec): Jan 7 15:37:00 asterisk_pbx[5038]: Jan 7 15:37:00 DEBUG[1234379840]: File app_festival.c, Line 400 (festival_exec): Jan 7 15:37:00 asterisk_pbx[5038]: Jan 7 15:37:00 DEBUG[1234379840]: File app_festival.c, Line 410 (festival_exec): Jan 7 15:37:00 asterisk_pbx[5038]: Jan 7 15:37:00 DEBUG[1150495040]: File chan_sip.c, Line 567 (__sip_ack): Jan 7 15:37:00 asterisk_pbx[5038]: Jan 7 15:37:00 DEBUG[1150495040]: File chan_sip.c, Line 567 (__sip_ack): Jan 7 15:37:01 asterisk_pbx[5038]: Jan 7 15:37:01 DEBUG[1234379840]: File cdr_addon_mysql.c, Line 123 (mysql_log): Jan 7 15:37:01 asterisk_pbx[5038]: Jan 7 15:37:01 DEBUG[1234379840]: File cdr_addon_mysql.c, Line 130 (mysql_log): Jan 7 15:37:01 asterisk_pbx[5038]: Jan 7 15:37:01 DEBUG[1234379840]: File chan_sip.c, Line 1081 (sip_hangup):

I can restart Asterisk again, and do this over and over and over. If I use the -g option to generate a core dump, I never see one generated.
Any thoughts on what might be happening here? What am I doing wrong?
