We had a call the other day from someone with a Vodavi Inspire (per my tech) ... they bought a phone off the internet .. and it doesnt work right

my tech said it comes up and says 12 button lcd... but wont respond

any thoughts? .... there isnt much work for us so i am ok with telling her she has to call her original vendor (we lost the deal way back when) but she doesnt like him .. but if it is easy enough i would help her out and make a couple bucks

thanks
