What is a Telephone System?

A telephone company or carrier, provides you with phone lines that provide dial tone and phone numbers which allow you to make and receive phone calls.

These phone lines plug into your business phone system (PBX) which provide advanced business features.

Here’s what happens….A phone call comes over your phone lines into your office phone system and is routed by the phone system to either an individual user, an Automated Attendant (press 1 for this or 2 for that), or to a Call Group which is a group of users handling calls to a department (i.e., Customer Service, Technical Support, Accounting).

The business phone system is the brain that routes your incoming calls to right user or call group. Modern PBX systems offer a variety of popular features such as call recording, faxing, music on-hold, announcements on-hold, desktop and mobile apps, IM other employees, call processing rules…such as ‘ring my desk phone, if no answer roll to my mobile phone, if still no answer, send the call to my office voice mail, and email the voice message to me. That is only one example of a customizable call handling rule and makes this a perfect solution for the small business phone system to enterprise business phone system on the market.

Types of Office Phone Systems?

There are two types of office phone systems: On-Premise (installed at your office) and Hosted (also referred to as Cloud-based). Dynam Communications offers both solutions depending on your communication strategy and budget. If you have a lot of phone users and prefer for your equipment to be behind your office firewall, then on-premise may be the best fit and most economical.

If on the other hand, your immediate concern is keeping costs low, you may wish to consider our hosted office phone systems for small business. With hosted, we are your phone company and your phone system. This means you don’t have to pay a phone company, like AT&T, so they can use your money to buy naming rights to sport stadiums, downtown squares, and a ton of cable TV channels and other companies. That’s why we’re able to charge about 65% less than AT&T and other phone companies.

The No Brainer”

Phone companies like AT&T just provide you with dial tone and phone numbers. We charge about 65% less and provide dial tone, phone numbers, fax numbers, faxing, music on hold, call recording, automated attendants, call groups, IM, allow employees to work from home or around the country but make/take phone calls just like they are in the same building. We also provide visibility so your employees can see if each other are on a call, in a meeting, out to lunch, and so many more features!

We’ll let you name sport stadiums, buy HBO, and name downtown squares. We’ll just focus on providing the best and most affordable large and small office phone systems and service in the country.

Rather than an on-premise phone system you might choose our Hosted, or Cloud-based Office Phone System. Our hosted phone system is where we install business phones at your office which register remotely to our phone service in the cloud. Dynam Communications would be your phone system and your phone company.


  • If you lose power or internet at your office, your callers can still call your phone numbers. Accordingly, during an outage, we can forward your calls to voice mail, answering service, or to a mobile phone.
  • Rather than a large upfront cost in investing in an office telephone system, the cost of service is a small monthly fee and often much less than what you are paying a phone company for just dial tone.
  • Free long distance. So, the whole country is a local call.
