Voip Pbx Or Conventional Pbx Telephone System
To stay with your Traditional PBX or throw it away in favor of Internet Telephony?
Why to reject services which would promise to improve the productivity?
Substitute the Traditional PBX for a modern Voice over IP PBX and take all the benefits this new technology offers.
How to proceed?
You can decide whether to have:
- analog,
- digital, or
- IP phones
on your desk and if to go with TDM or VoIP phone services to be linked with the outside. With some systems you’ll be able to mix.
Which one is the right solution for me?
TDM?
VoIP?
or Both?
Why not?
Many phone system that handles more phone handsets gives you an option on how to connect phones to the PSTN.
A pure Voip Telephone Service system operates totally in the IP world from handset to call termination. The equivalent to the traditional PBX is the IP PBX. The IP PBX 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. Calls from and to non-subscribers are terminated to the PSTN at the provider’s location.
Most of the time, you can mix purely analog phone systems, purely digital and TDM phone systems and purely VoIP phone systems. A Voip system may well have FXS (Foreign Exchange Subscriber or Station) ports to connect to analog handsets, as do traditional PBX phone systems. The phone service connection can be ISDN, T1, analog or SIP Trunking.
Most of the time, modern Voip PBX phone systems offer a broader range of handset and phone service connection options than legacy PBX systems. Before you make any big purchases or plans to scrap you current phone system, you should consult an expert or look for relevant information in one of the many Voip Review Sites you’ll find online.
