Allworx has been making VoIP business phone systems for quite sometime now, so there are many of these deployed systems successfully handling business communications. There are many of the 6x, 10x, 24x and 48x systems out in the field. These IP-PBX systems have maintenance software that allows admin to create backups and restore those backups if needed. Setting up a backup system routine is important for recovery in the event of a large failure or other critical event and should be part of a (phone) IT person's duties. Once initially setup they will complete it at a scheduled time, usually done as an incremental backup, correcting any new changed settings so that the systems settings are matched, current and backed up.
For Allworx system backups and to restore a backup you need the Office Safe Backup Tool.
Allworx has been providing IP phone systems for some time now and there are thousands installed in businesses worldwide. Original models of their ippbx were the 6x and 10x, which many are still found in many small companies, which the IT person is finding the need to administer. Now, Allworx Connect™ sells itself as a platform for the future and currently provides IP-PBX switches that range from two small business solutions, the Allworx Connect 324 and 320 that support up to 20 users, all the way to the 731 which can handle up to 180 users. They also currently offer two models of their own IP phones, the Verge 9308 and 9312.
