just about any system out now will meet your needs.
some things to consider:

The shop: HAve they been around a while? How long have they had the product? What type of warranties? How long will they give free programming changes? and what type of training.

Equipment. HOw much will it cost to add a phone later? is it a brand new release? or is it so old that it may be discontinued to where you will only be able to get refurb parts?

Grant it some systems are stronger than others and somettimes that strength comes with a strong price. Sometimes you can get a lot ofr bang for your buck but when you have a lot of problems because the software still has bugs...

Anyway it is best to shop for a quality Vendor and let them decide for you. A good shop would become a partner with you. Decide what you want the system to do and then what you would like the sytem to do. Make it clear to the shop that you decide upon. give a realistic price target and the shop will give you the best they have to offer. Then, scour message boards, find complaints and make sure the shop can address them to your liking. I don't know DTMF, but if his shop is as good as his knowledge on these boards you cana't go wrong.
