Noise instead of congradualtory message when dialing

A freshly installed Asterisk system (asterisk- picks up when dialed but instead of congradulatory message (as laid out in extensions.conf) all that is heared is noise.
The “context” part of zapata.conf file is set to “default” and the “default” context in extensions.conf points to [demo]:

inlcude => demo

and in [demo]:
exten => s,1,Wait,1
exten => s,n, Answer
exten => s, n, Set(TIMEOUT(digit)=5)
exten => s,n, Set(TIMEOUT(response)=10)
exten => s, n (restart), BackGround (demo-congrats)
exten => s, n (instruct), Background (demo-instruct)
exten => s, n, WaitExten
exten => 2,1, BackGround(demo-moreinfo)
exten => 2, n, Goto(s, instruct)

exten => 1000, 1, Goto(default, s, 1)

Also, the ffedback on Asterisk CLI console is only about ringing:

NOTICE[3204]: chan_zap.c:6061 ss_thread: Got event 18 (Ring Begin)…

and nothing about any execution of dialplan laid out in extensions.conf. What am I doing wrong and how to get to the congradulatory message?


exten => s,1,Wait(1)

instead of Wait,1
