OctWare's SoftEcho License Backup

On page 10 of the installation guide located in the base tarball package at this link:

They talk about it. I have the Sangoma card with built in licenses and it has let me re-register on different machines. If you bought the license you probably need to backup as explained below

It is EXTREMELY important to BACKUP the files found in /var/lib/octware/licenses directory.
This directory contains the Host-ID specific license files for the current system. These
licenses are locked to the MAC address of the Ethernet devices found on the system.
Creating a backup of this directory will allow a complete restoration of the OCTVQE channels
that were licensed using the register utility when doing a new operating system installation.
This will prevent unnecessary interactions with your key distributor, requesting authorization
to increment the Activation-Key that was already used.

I have used both and find that the Octasic solution is a lot better than Mark II. What happens with Mark II is that there is a lot of echo at first and then it learns the echo. This is not the case with Soft Echo, no echo from the start. It just works.

I had to tweak softecho a bit to suite my echo profile, but work perfectly now!
