Hello,

I am sorry you've had this bad experience and I apologize on behalf of
Sangoma if we gave you the impression of not caring about your technical
issue.

To rephrase what tech support meant. Our HWEC is known to provide better
results, but in no way that means that we will not look at your issue with
the card that does not have HWEC.

A senior tech support engineer will be contacting you soon today to follow
up on your issue appropriately.

Regards,

Moises Silva
