That seems to work. I had an error message first:

app_dial.c:1197 dial_exec_full: Invalid timeout specified: 'm'

but i just added a timeout value. How do the timeouts an the local channel 
work anyway? i added now:

exten => 18,n,Dial(Local/s at internals,30,m)

Does it mean after 30s this extension timeouts? I guess so but i try to 
understand. Sorry for thinking aloud.

Thank you again.
