If you should need to convert these back into readable files, use this perl script: (Jun/06), there is a sourceforge web site contains a perl script for manipulating all aspects of a GXP-2000 phone from the command lineknowing only the phone IP number.

It is recommended when issues are apparent and helping the end user is required.

Grandstream has released software in a variety of states - from stable, to very beta.

Using beta release software is tempting, but can be a risk.

The edited template file uses an asterisk server ip of 192.168.0.199and a router ip of 192.168.0.15.

There is a known issue with Grandstream phones that have the recent 1.1 beta firmware loaded.
