I think you may have a QC / installation process issue (aka provisioning), 
which you are trying to compensate for.

Instead of taking this stance, I suggest you look into how to make changes 
without someone screwing up something else by mistake. 
(hint.. changing stuff via scripts is one way to do this).

Why are you/your customers insisting on using GrandStream phone ? 

Just another suggestion:- 
We would much rather run a 'standard' based network, and not customize these 
types of settings on the Radios.. If we ran into this type of a situation, we 
would offer a managed router service (free or nominal charge), and or use a 
mikrotik router as a dmarc on the customer prem, and do all the funny business 
customization on that.
