Support for Variables

[Asanka]

Hi Guys,

This is an issue that we come across almost daily basis. We're an ISP with over 400 PBX customers and majority of them uses Yealink handsets.

Let me put a few scenarios where this would help especially with customers with a large number of handsets.

* DHCP Host name issues.
-- Some customers have issues with DHCP when all the devices have the same host name.
-- Some customers want to be able to identify which extension is configured from the hostname.
-- It is not feasible to change 100s of MAC.cfg files to accommodate this as there's no auto generate tool for this feature.

For this situation if we had a global variable for the extension number (Ex. $USER - Cisco), we could have easily incorporated it to the hostname in the base config file: Ex. $USER-T46G

* Line key and account Label.
-- Some customers would like to see their name on the top left corner (Account Label) and the extension number next to the DSS key.
-- At the moment we have to amend each file by hand if we're to do this and is not feasible for large distributions.

If we had the variable $USER as above, we could it with the base config file for the line keys.

It would be great if you guys could implement it this way or if we're allowed to use like below:

linekey.1.label = account.1.user_name
