[asterisk-users] Polycom (and others) digitmap info

[Jerry Jones]

There have been many threads regarding specific uses for digitmaps.

One of the most common is for the telephone to perform digit  
substitution and prepend some digits. Never thought this was possible  
until I found a reference in a Sipura tech note .

Anyway hope this helps someone.

Add something like <:9>xxxxxxxxxx to your digitmap and it will  
prepend a 9 to the 10 digit number. Tried on my Polycom phone and  
works great for just hitting dial when reviewing missed calls. Did  
have a pattern match in my dialplan but it created other issues and  
was removing it. This may actually work better.
