We purchased an Allworx 6x in 2008 and have varied results with the system over the years. Very recently we had some intermittent rebooting issues we believed to be caused by a 5 year old Compact Flash card which has accumulated many write cycles (256mb is what came with the system at the time).
We asked our rep what cards would work and he felt it should be a type ii CF card. At first the reference seemed to be to the CF type itself but it turns out it is a reference to the speed types offered by Sandisk. Sandisk offers different speeds such as Ultra (ii), Extreme (iii) and Extreme Pro (iv). Apparently there are potential write issues with the iii or iv so we went with the maximum we saw currently supported by Allworx in that family which is a Sandisk Ultra II 2GB (a massive upgrade over our 256mb older, slower card).
The simplest information I found was actually in their marketing information to validate this. On Page 6, there is the reference “Compact Flash Slot – Accepts Ultra 2 SanDisk Compact Flash card” in the pdf below:
In the end, it cost ~$13 and worked. I bought some spares because of the extreme low cost. We do backups to a server (whose automation is broken for reasons we haven’t investigated) but we are able to do manual backups. To get this process to work, I had to install Office Safe Backup 5.3.1 (click here to download) on my laptop and copy our backup directory to it to restore from the backup. I had to set my laptop on their network with a direct connection.
Installing a new Compact Flash Card is described in the installation guide below on Page 8:
The backup and restore process is described in the Administration Guide below on Page 75:
In the end, the process worked. Getting the new compact flash card installed and operating was simple but it was the restore process which took a little more time and was less sensible. It was needlessly convoluted spanning multiple documents, steps of validation and having to do everything from a laptop when the restore process could easily have been accomplished like a router flash upgrade.
