Grandstream Digit Map / Dial Plan

August 2016

***This article is for informational purposes only. This is not a standard feature of the OnSIP Hosted PBX and is unsupported.***

You are welcome to use the following information to enhance your OnSIP Experience, but technical support is not available from OnSIP for this feature. For assistance beyond the below document you will need to contact the hardware manufacturer/reseller directly.

As part of adding your Grandstream phone to the boot server, the field called "Custom Digit Map" is where the following digit map/dial plan would be added.

The dial plan adds a 1 to any 10 digit number that begins with 2 through 9, but allows for 11 digit numbers that begin with 1. This plan also allows for the * to be dialed, so *98 works, and it allows for extension numbers of any length.

{<=1>[2-9]xxxxxxxxx | [1]xxxxxxxxxx | *x+ | xx+}
