Shall I Purchase A IP PBX?
Shall I Purchase A IP PBX (News - Alert)?
Should you keep your conventional phone system or throw it away in favor of Voice over IP?
Why to reject services which would increase the value of the productivity of your office?
Replace it all for a modern Voip system and take all the advantages this new technology offers.
How to proceed?
You have more than one choices:
- analog,
- digital, or
- IP phones
each desk and whether to go with TDM or VoIP to be linked with the outside. With some systems you'll be able to mix and match.
Which one to take?
TDM?
VoIP?
or Both?
Why not?
Most phone system that handles a few phone handsets gives you the option on how to connect phones to the PSTN.
A pure Voice over IP phone system operates entirely in the IP world from handset to call termination. The PBX equivalent is the Internet Protocol PBX. The Internet Protocol PBX is generally a software running on a Linux system. The handsets are referred to as SIP phones.
SIP is a switching protocol that controls the phone calls over the Internet. Calls between subscribers to the same Voice over IP service provider stay completely on the network and never enter the PSTN. Calls from and to non-subscribers are terminated to the PSTN at the provider's location.
Generally you can mix and match 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 phone systems. The phone service connection may be T1, analog, ISDN, or SIP Trunking.
Usually modern IP PBX phone systems can offer a wider range of handset and phone service connection options than traditional PBX systems. Before you decide to replace your phone system, you should consult an expert or search for related information in one of the many Voip Review Sites you'll find online.
