Nice idea! This works a treat (as a nasty hack) - it falls back to the
default context, which just happens not have an "s" extension like
this...

    -- Detected ring pattern: 247,159,0
  == Starting Zap/3-1 at main-line-7711,s,1 failed so falling back to
exten 's'
  == Starting Zap/3-1 at main-line-7711,s,1 still failed so falling back
to cont
ext 'default'
Sep 27 14:17:04 WARNING[19476]: pbx.c:1877 ast_pbx_run:  Channel
'Zap/3-1' sent
into invalid extension 's' in context 'default', but no invalid handler 

Thanks for your help
