To set IP address ranges and assign codec profiles to them, in AltiEnterprise Manager
click the IP Codec tab.
By default, all private addresses are set to G.711 codec only. You can add individual IP
addresses and address ranges and assign a codec to each.
To add IP addresses and address ranges and assign a codec
1. Click the Add button in the IP Device Range panel. The Add IP Device Range dialog
box opens:
2. Enter an IP address range (for dynamic IP addressing), or enter the same address
in each field if this is a static address. You cannot use the minimum and maximum
values (0.0.0.0. and 255.255.255.255).
3. Click OK.
If you have multiple AltiGateways controlled by an AltiWare host system, you need to
configure an Inter Gateway Codec profile.
