It's a pattern matching thing; the asterisk module "knows" how to process stdexten, but thinks that "n" or "N" is a digit substitution. When "n" or "N" is "escaped" ([n] or [N]) the program knows to treat it as a literal and not a pattern match.

Also, the prefix "_stdexten-." seems to work fine in the [stdexten] context, so I'm not sure what's different here. -- _____________________________________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
