Where to maintain a large telephone customer base?

Question

Database

There was a need to have a database of customer phones. The base is large (cold), regularly added. I would like to have a convenient export / import, it is desirable to bring phones to the standard (that is, when importing, phones are usually somehow clogged), custom speakers and noisy access.
I have never worked with 1s, I want to ask the craftsmen - is there no accidentally necessary solution for me?

Answer 1

There are ready options. For example, infostart.ru/public/295443
On the eve of the new year, I can write a simple configuration according to the TK for free :)

Answer 2

Is MS Access which as a rule at offices already is.
Plus Google docs.
But this is all average.
