Network Configuration Guidelines for VoIP
Real-time applications such as voice communications require a networking
environment that meets certain requirements to deliver and maintain good
voice quality. The following network configuration guidelines are highly
recommended when using AltiWare's VoIP features.
ISP/Intranet Quality of Service (QoS)
•
If you subscribe to the public IP network or use your own Intranet,
make sure the maximum network delay is less than 150 milliseconds.
•
Also, the typical packet loss rate should be less than 5 percent.
WAN Bandwidth
•
If you are running G.723.1 compression, you should reserve 17 kbps
WAN link bandwidth for each channel.
•
You should reserve a minimum of 75 kbps WAN link bandwidth for
each IP G.711 channel.
•
When a small data application (e.g. one FTP transfer session) is
running across the same WAN as AltiWare IP, make sure bandwidth
is reserved for data traffic. An example would be, if you have 64 kbps
WAN link, you can run one G.723.1 session concurrently with one
FTP file transfer session, provided that the router fragments each TCP
packet to 500 bytes.
