All phone systems are basically able to send and receive local as well as long-distance calls across the world. The usual features they share are call waiting and call forwarding, caller identification, and remote access. But businesses need more than these and perhaps one of the extremely useful features of today's business phone systems is the auto-attendant. This feature receives calls with an automated response, which includes a menu of options basically directing the customer to press certain numbers if they wish to speak with so or so; for example 1 for sales, 2 technical, and so on. Changes can be automatically activated after working hours and during weekends.
Most of these systems play music when putting the customer on hold, so they will not feel like they have been transported out of this world while waiting for somebody to get back with them. The more advanced systems can even be programmed to play different melodies for different kinds of customers. http://www.ehow.com/how_4923317_install-phone-system.html
The system must be capable of unlimited extensions and each extension must have some response message from the employee, which is activated every time nobody is available to receive the call. Also, it should enable caller identification, voice mail, call forwarding to another station where the employee maybe currently at, as well sending calls when the employee is not around. A particularly invaluable feature is the "hot desk," which enables employees to bring along their voice mail and calls as they move from one desk to another.
TPC Business phone systems should have a line dedicated to voice transmissions and separate one for data transmissions in order to handle both. A T1 voice system can accommodate 24 channels and 24 detached numbers for every phone line. The TI is also used to access the Internet and the speed for downloading and uploading vary from equipment to equipment. An integrated T1 system can accommodate data and voice altogether on the same line. Voice over Internet Protocol/VOIP system allows phone calls via the Internet. The advantages of using VOIP include being able to make free phone calls from around the world when you are plugged into the net.
It is important that a business phone system can handle conference or group calls. A good phone system allows a limitless number of in-house participants and a number of external callers that is equal to the number of phone lines. Some systems can even accommodate external callers in an unlimited number. And with the popularity of video conferencing nowadays, phone systems can be utilized not only for voice calls but video images as well. View website if you have questions.
