HAI Omni II Board Test

[TheCodeMan]

I am replacing my HAI Omni II with a HAI Omni IIe so I will be selling my board and software. Is there a test I can run against the board to be sure all circuits are working properly?
 
I recall seeing something about a self test using one of the keypads. I had some issues with the phone circuitry where I would call and sometimes could get connected and other times it would just disconnect. Everything else worked fine on the panel when I pulled it. 
 
I had the panel pretty much maxed out with four keypads and two expansion panels.
 
Any idea what I might look to charge for the panel and user software (not dealer) given a possible telco issue?
 
I'm sure the board is long since out of warranty so I doubt HAI would repair it at this point.
 
For a DIY'er who has electronics experience, it might be a bargain.

I have never seen a self test, and that would be hard because many of the circuits depend on outside factors. I have had several boards over the years and the failure has always been in the phone area. That seems to be a HAI weakness. It can be pretty temperamental as well.

Any idea what the value of the board and user software might be worth given this issue? I will also be including the HAI lockable metal enclosure and an AC adapter for the board along with hard copies of the installer and user manuals.
 
Does anyone on this board do HAI board level repairs?
