Network Configuration Guidelines for the Alti-IP
600 Series of IP Phones
The following guidelines (specific to the Alti-IP 600 series of IP phones)
should be taken into consideration as a precursor to configuring your
network for use with NAT (see
Network Configuration Guidelines below).
• DHCP is recommended to reduce the risks for duplicating IP
addresses. AltiContact Manager provides seamless support for
AltiGen IP Phones using dynamic IP addresses. Select Dynamic IP
address for IP Extensions in ACM Admin.
• A switch is recommended at the corporate network, rather than a hub,
for IP phone connection. This can reduce packet loss ratio.
• If there are not enough IP addresses in the corporate network, refer to
“Private and Public Network Configuration (AltiWare with Both
Private and Public IP Addresses)” on page 9-21. If DHCP is used in
this configuration, the administrator will need to perform the following
for the Alti-IP 600:
1. Configure the DHCP server to assign a private network IP address
for each phone based on the phone’s MAC address (printed on the
label on the bottom of the IP Phone.
2. Private IP address needs to be added to AltiServ and TFTP server
as well.
3. Launch an AltiGatekeeper with private IP address and point to
AltiWare’s private IP address.
