Hello,
before I open a Jira ticket, as I might be overlooking something.

I am trying to use say_string. Documentation is lacking so all we have is here:
http://wiki.freeswitch.org/wiki/Misc._Dialplan_Tools_say

But when I try to use it in the CLI i get:

freeswitch@192.168.2.154@internal> eval ${say_string en.wav en current_date_time pronounced ${strepoch()}}
file_string://time/mon-4.wav!digits/19.wav!digits/2.wav!digits/thousand.wav!digits/14.wav!time/at.wav!digits/1.wav!time/oclock.wav!time/p-m.wav

As we can see, say_string is not generating full path to the files so when i try to use it with application playback for example I get "FILE NOT FOUND" response from FS.

The say application itself works, so I suspect this is a bug, but since this behaviour happens with both latest head

and a very old commit that I have in another machine:

I am inclined to think I am missing some configuration for this to work.
