IP Or Standard PBX?
By: Jim Francisto
Should you stay with your traditional PBX telephone system or throw it away in favor of Voip?
Why to miss services which would promise to enhance the productivity?
Substitute it all for a modern Internet Telephony phone solution and take all the advantages this relative new technology offers.
What to do?
You have several choices:
- analog,
- digital, or
- IP phones
on your desk and if to take TDM or VoIP to be linked with the outside.
With some systems you'll be able to mix and match.
Which one to choose?
VoIP?
TDM?
or Both?
Why not?
Most telephone systems give you the option on how to connect to the PSTN (Public Switched Telephone Network).
A pure Voice over IP telephone system completely operates in the IP world from handset to call termination.
The equivalent to the traditional PBX is the IP PBX.
The IP PBX is mainly a software running on a Linux system.
Handsets are referred to as SIP phones.
SIP or Session Initiation Protocol is a switching protocol which controls the telephone calls over the Internet.
Calls between subscribers of the same Voip service provider completely stay on the network and never enter the PSTN (Public Switched Telephone Network).
Calls from and to non-subscribers are terminated to the PSTN at the provider's location.
Most of the time, you can mix purely digital and TDM phone systems, purely analog phone systems and purely VoIP phone systems.
A Voice over IP system may well have FXS (Foreign Exchange Subscriber or Station) ports to connect to analog handsets, as do traditional PBX telephone systems.
The telephone service connection can be T1, analog, ISDN, or SIP Trunking.
Normally modern Voip PBX telephone systems offer a wider range of handset and telephone service connection options than traditional PBX systems.
But before you decide to replace your telephone system, you should ask a skilled expert or search for relevant information in one of the many Voip Review Sites you'll find on the Internet.
