Various alphabet characters have special meanings in extension patterns: 
n, x, z, etc. The 'n' in 'listener' is not being matched to a literal 
'n', it's looking for a digit between 0 and 9.

To work around this, you'll need to use '[n]' instead of 'n'. This has 
nothing to do with Local channels, by the way, it's just how extension 
pattern matching works.
