Should you stay with your conventional PBX or throw it away in favor of an IP Phone System?

Why to miss services which would promise to improve your productivity?
Substitute it all for a modern Internet Telephony solution and take all the advantages this new technology provides.

How to proceed?

You can decide whether to have:
- analog,
- digital, or
- IP phones
on your desk and if to go with IP-telephony or TDM to connect with the external world. With some systems you’ll be able to mix and match.

Which one to select?
VoIP?
TDM?
or Both?
Why not?

Most any phone systems give you the option on how to connect to the PSTN or Public Switched Telephone Network.

A pure IP Telephone System completely operates in the Internet world from handset to call termination. The equivalent to the traditional PBX is the Voip PBX. It is generally a software running on a Linux system. Handsets are referred to as SIP phones.
SIP (Session Initiation Protocol) is a switching protocol which controls the phone calls over the Internet. Calls between subscribers to the same Internet Telephony service provider never leave the network and never enter the PSTN or Public Switched Telephone Network. Calls from and to non-subscribers are terminated to the PSTN at the location of the provider.

Most of the time, you can mix and match purely analog phone systems, purely digital and TDM phone systems and purely VoIP phone systems. A Internet Telephony system may well have FXS (Foreign Exchange Subscriber or Station) ports to connect to analog handsets, like traditional PBX phone systems. The phone service connection may be T1, analog, ISDN, or SIP Trunking.

Usually the newer IP PBX phone systems offer a wider range of handset and phone service connection options than traditional PBX systems. But before you make any big purchases or plans to scrap you current phone system, you should ask an expert or look for related information in one of the many Voip Review Sites you’ll find on the Internet.
