Choosing Your Small Business VOIP Phone System in Tampa

When choosing your small business VOIP phone system in Tampa, you should definitely consider the services of Digital South Communications.

It offers maintenance of existing phone systems; local and long distance phone service; IP/VoIP telecommunications solutions; digital phone systems with IP/VoIP potential; SIP trunking; Voice T1; ISDN PRI T1; used phone systems and voice mail with warranty; computer networking; internet access; recording of phone calls, emails, screen shots and instant messaging; promotions on hold; loudspeaker paging and music for offices or plants; and voice and data cabling.

Digital South Communications can provide your business with the NEC phone system, BCM phone system or Vertical phone system. Since Norstar/Nortel has already been sold, Digital South Communications extends the discounted upgrading offer of the NEC phone system to Norstar/Nortel customers who may be experiencing problems with the turnover.

A VoIP phone system means Voice over Internet Protocol. This phone system delivers voice communications over the internet and other IP networks instead of the public switched telephone network or PSTN. This is why it is also referred to as IP Telephony or IP Telephone System. This is considered as a digital phone system because the analog voice signal is converted to digital format and translated into internet protocol packets in order to be transmitted through the internet.

SIP / VOIP phones are required for the VoIP phone system. The various types of SIP / VOIP phones are software based SIP / VOIP phones, USB SIP / VOIP phones and hardware SIP / VOIP phones.

Software based SIP / VOIP phones, also called soft phones, are actually not physical phones but programs. The program is installed on the computer and it allows the user to make calls through the computer's microphone and its speakers or a headset.

USB SIP / VOIP phones look physically like the regular telephones. They are plugged into the computer through the USB port. They also need the soft phone software to work, though.

Hardware SIP / VOIP phones not only look like regular telephones but also function just like them. They contain an integrated mini hub and are directly connected to the data network of the computer, thereby sharing the network conection. There are several popular brands to choose from.

Voice and data cabling should be installed properly for the telecommunications and information technology systems of a company to perform properly. Digital South Communications does voice and data cabling from single locations to thousands of locations; voice and data cabling in existing or newly constructed offices; complete data center installation including wall and floor racks and cabinets; coax and video cabling; Cat 3, Cat 5e, and Cat 6 data cabling; fiber optic cabling; underground cabling between buildings; aerial cabling such as the setting up of telephone poles; installation of cabling for office and warehouse paging systems; testing, labeling, and certification of cabling; installation of cables and jacks for phones and computer networks; and building entrance protection.

As a member of the Building Industry Consulting Service International, Inc. (BICSI), Digital South Communications complies with the BICSI Code of Ethics and the BICSI Registered Communications Distribution Designer (RCDD) Standards of Conduct. That includes primarily working according to the regulations of the National Electrical Code as well as all local regulations and the highest standards of the low voltage voice & data cabling industry.

Digital South Communications has efficiently provided over 3,000 clients with small business VOIP phone systems and other services since 1991. The company's main client base is in Tampa but it also serves the entire state of Florida and the rest of the country through its affiliated network of dealers.
