[Asterisk-Users] Festival problem

[Gareth Blades]

I have Festival running fine on one Fedora Core 3 machine but I am
having problems getting it to work on another one.
I am using festival-1.4.2-25
I have followed the guide at
http://www.voip-info.org/wiki-Asterisk+Festival+installation and am
using the second festival command patch which is the same one I use on
the working server.

The festival logs show the following on the working machine:-
"Load server start ./festival_server.scm"
 festival port=1314
wrapper Thu Mar 17 14:59:10 GMT 2005 : USING DEFAULT CONFIGURATION
wrapper Thu Mar 17 14:59:10 GMT 2005 : waiting
server    Thu Mar 17 14:59:10 2005 : Festival server started on port
1314
client(1) Tue Mar 22 15:10:53 2005 : accepted from voip
client(1) Tue Mar 22 15:10:54 2005 : disconnected

On the non working machine :-
"Load server start ./festival_server.scm"
 festival port=1314
wrapper Tue Mar 22 15:29:25 GMT 2005 : USING DEFAULT CONFIGURATION
wrapper Tue Mar 22 15:29:25 GMT 2005 : waiting
server    Tue Mar 22 15:29:25 2005 : Festival server started on port

asterisk.linguaphone-intranet.co.uk
client(1) Tue Mar 22 15:33:35 2005 : disconnected

On the working server asterisk shows :-
   -- Executing Answer("SIP/7152-d36e", "") in new stack
    -- Executing Wait("SIP/7152-d36e", "1") in new stack

On the non working server asterisk shows:-
    -- Remote UNIX connection
    -- Executing Answer("SIP/6152-d2ec", "") in new stack
    -- Executing Festival("SIP/6152-d2ec", "mary had a little lamb") in
new stack

Any idea what is wrong?
What is this 'remote UNIX connection'?

Thanks
