For me, well, telephones wouldn't work without electricity :|
The Ubaid are considered the first agents of civilization in the region.
You failed to list the invention to consider.
If you are referring to the Dutch lens maker who was born in 1585 then there is probably no connection. He is sometimes credited with the invention of the compound microscope and associated with the invention of the optical telescope. However, these events would have happened long before the telephone company came into existence. For more information please consider viewing his page on wikipedia.
Many consider Nikola Tesla's best invention to be his development of the alternating current (AC) electrical system, which revolutionized the way electricity is transmitted and utilized. This system is still widely used today in power grids around the world.
It is subjective to determine the greatest invention as it depends on individual perspectives and needs. Some may argue that the internet is the greatest invention due to its vast impact on communication and access to information, while others may consider inventions like electricity or the wheel to be the greatest for their foundational role in shaping civilization.
it wasn't a discovery it was a invention and it was important because it made communication a lot shorter. If it wasn't invented somethings we have today that use sound waves to transfer a voice wouldn't had been invented or it would be a lot different. If the telephone had never been invented consider the following: You would still be sending a U.S. Postal message just to communicate with someone, or visiting. You would have no instant control of nearly every aspect of your life that you do not even consider today. You would not have been able to ask ANY questions such as you have because there would be no internet (Internet started with dial up modems.

Some points to consider when selecting telephone equipment include size, location, number of phones, special options, and whether to buy or lease.
Either writing, or the wheel (:

Trees being cut down for telephone lines I consider people tracking me through my cell phone a disadvantage ;) Non-private conversations. (actually, that is sort of bittersweet) The waste in electricity to run the power lines and phone Money for the electricity. (When you charge it. Even if it's wireless or wired)
Yes a telephone directory is a telephone book. Which includes listings of all the numbers of people in a certain area. I myself would consider a telephone directory any list or book that includes a list of people and phone numbers that are in a certain area.
