trixbox CE 2.6.1 has already had OpenVox Support

Important Info for trixbox CE 2.6.1

For most people, trixbox CE 2.6.1 isn't going to represent any major changes to what you have been used to in the past. There are a few things that are a little different that you should be aware of.

Setting up PSTN Cards
In order to create a framework for future features, please start using setup-pstn to configure your Digium or OpenVox cards. For Rhino, first run setup-rhino, reboot, and then run setup-pstn. For Sangoma, install the wanpipe utils and driver, reboot, and then run setup-sangoma.

Postfix
Postfix is now the default mail transport in trixbox CE, this was done due to popular demand. Postfix is quite simple to setup and manage. Along with this change we now have a General Settings module which has basic mail settings for relaying and authentication. From the command line are three new scripts:
setup-mail - Walks you through setting up Postfix and will help setup a relay server
install-sendmail - If you prefer sendmail, this script will switch you back
install-postfix - If you are upgrading from a previous version, the upgrade does not switch you to Postfix, this script will do that for you.

SNOM Support
The Endpoint Manager now supports all SNOM phones including the M3 DECT phone.

OpenVox Support
Expanded support for OpenVox cards is now included

Expanded Aastra Support
Support in the Endpoint Manager was added for Aastra 5 and 9 series phones and the Aastra XML services are now installed by default.

Cohesive Interface
We are making strides to provide a much more cohesive user interface that will look more professional and integrated. In order to avoid trademark issues, we had to remove all references to FreePBX and Asterisk, the Asterisk menu is now called PBX, and the FreePBX menu item is now called PBX Configuration.

Bulk Extensions
A new module is now included that will allow you to import a CSV file for bulk extension creation.

Upgrading from previous versions

If you are upgrading from a previous version there are a few ways to accomplish this. From 2.6.0.7, install the newest version of tbm-Backup and backup your old system and restore it onto a new system. You can also upgrade an existing machine from 2.6.0.7 to 2.6.1 by using the Package Manager or via a yum update.

For older versions, it is recommended that you update FreePBX to the current 2.4 version and install the FreePBX backup/restore module. Use this tool to backup your existing system. On the new system install the backup module from the module admin tool and restore the backup to the new system. To continue to do backups on the new system it is recommended to use the trixbox Dashboard backup module since it backs up more information than the one in the PBX Configuration tool.
