The pound sign (#) at the end of the digit map causes the IP Deskphone to dial the matched dialing
plan immediately.
DRegex
The Digit Regular Expression (DRegex) syntax is a telephony-oriented mapping of Portable
Operating System Interface (POSIX) Extended Regular Expressions (ERE). Users must take care
not to confuse the DRegex syntax with POSI EREs, as they are not identical. In particular, there are
many features of POSIX EREs that DRegex does not support. The dialing plan uses DRegex
instead of ERE. The following rules demonstrate the use of DRegex.
