VoIP services are generally more price competitive than the incumbent fixed line providers. Savings can be achieved through more cost effective line rentals, as well as discounted call rates. VoIP providers also offer a substantial discount when calling between branches or other users on their network (known as On-Network). It is becoming clear that traditional telco providers cannot compete with Voice over IP.
The beauty of Voice over IP is that you can take the service with you, make and receive calls from anywhere provided you have internet connection.
Flexibility and Scalability
You are able to have more than one phone number on a single internet broadband line, and adding additional lines only requires increasing the size of the internet line - allowing superior scalability on the fly.
You have the option of incorporating extra features into your service - quickly and easily! These extras include features such as Hunting Facility, Direct line numbers, Caller ID, etc which are often standard features with a VoIP service.
For Incoming Calls, your VoIP number could be Non-Geographic (i.e. 087) it is not tied to a specific area or line - you could appear to be a national company and can keep the same number wherever you go. You do however also have the option for other numbers such as 010, 020, etc - just enquire with your provider.
