Advantages of VoIP
Cost
In general, phone service via VoIP costs less than equivalent service from traditional sources but similar to alternative Public Switched Telephone Network (PSTN) service providers. Some cost savings are due to using a single network to carry voice and data, especially where users have existing under-utilized network capacity they can use for VoIP at no additional cost. Some Internet connections are asymmetrical, i.e. the upstream data rate is significantly lower than the downstream data rate. This places a final absolute throttle to the transmitted data rate and thus voice quality. The slowest Internet connections can offer lower signal quality than regular dedicated phone networks.
VoIP to VoIP phone calls on any provider are typically free, whilst VoIP to PSTN calls generally costs the VoIP user. Free VoIP to PSTN services are rare. A notable provider is VoIP User.
There are two types of PSTN to VoIP services: DID and access numbers. DID will connect the caller directly to the VoIP user while access numbers requires the caller to input the extension number of the VoIP user. Access numbers are usually charged as a local call to the caller and free to the VoIP user while DID usually has a monthly fee. There are also DID that are free to the VoIP user but is chargeable to the caller.
Functionality
VoIP can facilitate tasks that may be more difficult to achieve using traditional phone networks:
- Incoming phone calls can be automatically routed to your VoIP phone, irrespective of where you are connected to the network. Take your VoIP phone with you on a trip, and anywhere you connect it to the Internet, you can receive your incoming calls.
- Call center agents using VoIP phones can work from anywhere with a sufficiently fast Internet connection.
- VoIP phones can integrate with other services available over the Internet, including video conversation, message or data file exchange in parallel with the conversation, audio conferencing, managing address books and passing information about whether others (e.g. friends or colleagues) are available online to interested parties.
VoIP allows users to travel anywhere in the world and still make and receive phone calls:
- Subscribers of phone-line replacement services can make and receive local phone calls regardless of their location. For example, if a user has a New York City phone number and is traveling in Europe and someone calls the phone number, it will ring in Europe. Conversely, if a call is made from Europe to New York City, it will be treated as a local call. Of course, there must be a connection to the Internet to make all of this possible.
- Users of IM based VoIP services like Skype, Gizmo Project or Yahoo! IM can also travel anywhere in the world and make and receive phone calls.
