To keep your conventional Telephone System or toss everything out in favor of an IP Phone System?

Why to reject services which would promise to improve your productivity?
Replace it all for a modern Voip phone solution and take all the benefits this new technology provides.

What to do?

You have these possibilities:
- analog,
- digital, or
- IP phones
on your desk and whether to take Voip or TDM to be linked with the outside world. Some systems will still permit to mix and match.

Which one is the right solution for me?
VoIP?
TDM?
or Both?
Why not?

Most any Telephone Systems give you the option on how to connect to the PSTN.

A pure IP Phone System operates completely in the IP world from handset to call termination. The PBX equivalent is the IP PBX. The IP Phone System is generally a software running on a Linux system. The handsets are referred to as SIP phones.
SIP is the switching protocol that controls the telephone calls on packet based networks. Calls between subscribers of the same Voip service provider completely stay on the network and never enter the PSTN. Calls from and to non-subscribers are terminated to the PSTN at the provider’s location.

Usually you can mix and match purely IP Phone System, purely analog Telephone Systems, purely digital and TDM Telephone Systems. An IP Phone System may well have FXS (Foreign Exchange Subscriber or Station) ports to connect to analog handsets, like traditional PBX telephone systems. The service connection can be T1, analog, ISDN, or SIP Trunking.

Generally modern IP Phone Systems offer a broader range of handset and telephone service connection options than legacy PBX systems. But before you decide to replace your telephone system, you may consult an expert or look for relevant information in one of the many Voip Review Sites you’ll find on the Internet.
