Why Use VOIP
VOIP is a very usefull tool in todays communication world. You can have telephone lines, extensions to remote workers, and linking office's making them as one telephone system, allowing internal calls between extensions, transfering lines from one site to another.
If you have a reasonable quality Internet connection you can get phone service delivered through your Internet connection instead of from your local phone company.
We recommend that you use VOIP in addition to traditional phone service, since VOIP service providers usually offer lower rates than traditional phone companies,

Types of IP Network
The speech quality depends on the type of IP network in use. Managed IP networks provide better speech quality compared to unmanaged networks such as the Internet, where quality of service cannot be guaranteed.
Examples of recommended IP networks
Digital Leased Line
IP-VPN (Virtual Private Network)
Frame Relay
Not recommended
Internet (including an Internet VPN)
Note
If packet communication cannot be established between the respective networks. In this case, you
need to configure the network settings (e.g., a VPN router when using an IP-VPN) to establish packet
communication.
Unlike an IP-VPN, which is set up over a network providers own IP network, an Internet VPN is set up
over the Internet. Internet VPNs are not recommended for VoIP communication because transmission
delays and loss of data are likely to occur.
Bandwidth Assessment for Virtual IP Extension
Required Bandwidth per IP Telephone for a Call
The required bandwidth depends on what combination of codecs and packet sending intervals is used. Keep
in mind the following points about the type of codecs and packet sending intervals, in terms of speech quality:
The speech quality of the codecs varies as follows: (High) G.722, G.711, G.729A (Low)*1
The shorter the packet sending interval, the higher the speech quality.
The higher the speech quality the IP telephones provide, the more bandwidth the IP telephones require.
*1 When the preferred codec of each party differs, the call will be established using the lower codec. For example, if the caller prefers
G.711 while the called party prefers G.729A, the call will be established using G.729A.
Required Bandwidth for Each Virtual IP Extension
To allow all IP telephones to make calls simultaneously, it is necessary to keep available the bandwidth required
by a IP Extension with the maximum number of IP telephones connected.
