Voice Over IP (VOIP) can offer savings and extra functionality over traditional telephony systems without compromising quality.
Savings can be made through infrastructure reductions as you only need and IP feed (such as broadband) and not expensive telephone lines or ISDN.
Additional savings can be made on each call through a variety of reliable VOIP service providers.
Finally, by linking in other offices, home workers or even clients and suppliers you can get free calls!
As VOIP based systems are computer based extra features can be easily added. These include automated attendant and Automated Voice Response (AVR) to handle inbound traffic and router it to the correct person, even out of hours, directory listings, called ID, music on hold and voicemail.
Sadly it doesn't quite make the coffee yet, but it does do almost everything else!
