I would definitely report your issue to Digium technical support so that 
we can correct whatever issue this might be.  It might be something very 
simple causing the problem (like X running or something like that) which 
is making the system's interrupt latency increase to something at an 
unreasonable level for Zaptel to operate properly.  In any case, it's 
possible that it's a very quick problem to fix and that technical 
support will be able to help you with.

Also, make sure before you try calling to verify that it's not an 
OpenVox card.  I have had customers who thought they were sold a Digium 
card, but were in fact sold an OpenVox card which did not perform as 
well as would be expected from our cards, causing some grief and 
confusion for them.  It can be confusing because they use the Digium 
driver and look like a Digium card to the driver.
