Network Configuration Guidelines for the Alti-IP 600
The following guidelines (specific to the Alti-IP 600 Phone) 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. AltiServ provides seamless support for AltiGen IP Phones
using dynamic IP addresses. Select Dynamic IP address for IP
Extensions in AltiAdmin.
• 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 6-18. 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.
Configuration Guidelines for NAT
Note: This section only applies to Alti- IP 600 phones or NetMeeting
integrated with AltiView. For third party IP Phones, refer to
AltiGen’s NAT Application Note.
The following section discusses the use of NAT (Network Address
Translation) with AltiWare IP functionality. Configurations and limitations
for using NAT are addressed, and network diagrams explain the topology
of these configurations. The first 3 examples involve AltiWare
configurations for remote IP phones with a public IP address, with a private
IP address behind NAT, and with both private and public IP addresses,
respectively. The last example involves configuration for a remote branch
office environment where multiple IP phones require connection to
AltiWare.
