A1 VoIP Requirements
48 Getting Started
To limit the number of VoIP channels:
• Set the status of the ports you wish to disable (starting from the highest-numbered port) to OUS .
For example, if you wish to use only 10 of the available 16 VoIP channels (i.e., disable 6
channels), set the ports 8, 7, and 6 to
OUS as shown below:
In this case, the equation for bandwidth calculation, based on the previous example, will be changed
as follows:
A1.2 Network Configuration
You must evaluate the structure of the existing network to see if a VoIP network can be implemented.
Below are the points that should be taken into your evaluation.
Is it possible to have static IP addressing?
Because the maintenance of the VoIP Gateway Card is carried out from a personal computer (PC)
through an IP network, the card must be assigned a static IP address.
Static IP addressing must be made possible even when the DHCP feature is used. For more details,
refer to "2.2.1 Network Parameters" in the VoIP Gateway Card Programming Guide.
Required Bandwidth
= (No. of Fax Machines × Required Bandwidth for the G.711 CODEC) +
[( 10 - No. of Fax Machines) × Required Bandwidth for Voice Communication]
= (2 × 87.2) + [( 10 - 2) × 31.2]
= 424 (kbps)
