[Asterisk-Users] festival in agi?

[Maciek Kaminski]

Are there any restrictions on what may be executed in AGI? I try in vain 
to execute festival command from AGI while it executes successfuly from 
dialplan. Say_digits also executes from AGI.

Here is agi fragment (i use pyst package):
...
agi.festival('Thank You for calling');
agi.say_digits('123');
...

and asterisk log:
class AGI: self.env = {'agi_accountcode': '',
 'agi_callerid': 'kamyk',
 'agi_channel': 'IAX[kamyk at kamyk]/51',
 'agi_context': 'default',
