Dual Xeon server and Debian4.0r1

when i load ztdummy asterisk hangs on trying to playback an audiofile

extensions.conf
[outgoing]
exten => 1,1,Playback(ss- 
noservice)                                                               
                                                                         
                exten => 1,2,Hangup

sip.conf
[0001]
secret=123456789
type=friend                                                              
                                                                         
                                         context=outgoing
disallow=all
allow=ulaw
host=dynamic
