No sound from Festival("Hello World"

Hi

Just wonder whether anyone manage to get Festival 1.95 works with Asterisk 1.6.1.0 on CENTOS 5. I am using X-Lite Softphone in the test.

I follow the instruction from the article at voip-info.org/wiki/view/Aste … stallation to setup the Festival with Asterisk.

I created an extension in extensions.conf

exten => 123,1,Answer()
exten => 123,n,Festival(“Hello World”)
exten => 123,n,Hangup()

From console of the Festival server, I could see the message
client(1) Wed Jun 10 01:19:47 2009 : accepted from localhost
client(1) Wed Jun 10 01:19:47 2009 : disconnected

From Asterisk -r console, I could also see the message
== Using SIP RTP CoS mark 5
– Executing [123@internal_calls:1] Answer(“SIP/1000-097b70d8”, “”) in new stack
– Executing [123@internal_calls:2] Festival(“SIP/1000-097b70d8”, “Hello World”) in new stack
== Parsing ‘/etc/asterisk/festival.conf’: == Found
– Registered SIP ‘2000’ at 192.168.19.1 port 5060
localhost*CLI>

However, in the X-Lite softphone, I could only see the words “Call established”, but I could not hear anything.

Is there anythings else that I need to set?

Any help is very much appreciated.

Thanks
Heng
