Having trouble with sounds (newbie)

I just installed the asterisk on centOS using yum. I have a basic dial plan set up to play digits back via a soft phone. Yet I never get anything back. I did a couple test calls to an outside SIP trunk, so i do not think it is a firewall issue. The Echo() function is working fine, and basic calls between a local softphone and an IP trunk group with a DID.

Also there is nothing in /var/lib/asterisk, and i can not find a sounds.txt file. maybe I need to install extra modules?

Here my dial plan:
exten => 2,1,NoOp()
same => n,Answer()
same => n,Wait(2)
same => n,SayDigits(123)
same => n,Echo()
same => n,Hangup()

and the verbose level 7 output from the console

== Using SIP RTP CoS mark 5
– Executing [2@fromSofties:1] NoOp(“SIP/softphone-00000001”, “”) in new stack
– Executing [2@fromSofties:2] Answer(“SIP/softphone-00000001”, “”) in new stack
– Executing [2@fromSofties:3] Wait(“SIP/softphone-00000001”, “2”) in new stack
– Executing [2@fromSofties:4] SayDigits(“SIP/softphone-00000001”, “123”) in new stack
– Executing [2@fromSofties:5] Echo(“SIP/softphone-00000001”, “”) in new stack
== Spawn extension (fromSofties, 2, 5) exited non-zero on ‘SIP/softphone-00000001’

and the config for the trunk group
[softphone]
type=friend
host=dynamic
secret=XXXX
nat=yes
context=fromSofties
allow=gsm
allow=ulaw
allow=alaw

I am getting the same lack of digits being played when I call in via the IP trunk group.
Any suggestions?

Thanks for your help

SOLVED
I used the installation instructions found at: voip-info.org/wiki/view/Aste … n+CentOS+6 and now everything is dandy.
