284 AltiWare ACC 5.1 Administration Manual
Enter the Public IP address of the router in the Public IP Addresses panel. (In the
example above, the address is 209.220.14.8.) Do not check Enable Virtual IP
Addresses Support.
5. Configure the NAT/firewall to forward TCP ports 10025, 10027, 10032, 10037,
10050, 10064, 1720 and UDP ports 69, 5060, and 10060 to AltiServ.
6. Configure the NAT router to forward to AltiServ UDP ports 49152 + gwid * 512 ~
49152 + (gwid * 512 + ipresno * 2) where gwid is the gateway id and ipres number
is the number of the IP resource channels in the system. (See note below for an
easier way to figure the port ranges.)
For the MAX1000 system, it would be UDP ports, from 49152~49211 (30 IP resource
channels).
Note: An easy way to find out the RTP/TCP port range(s) for SIP and H.323 is to look
in the Current Resource Statistics window in AltiWare Administrator (View >
Current Resource Statistics). All the ports are listed in the Local Ports
column.
Implementation details
After you complete the NAT configurations, the system will translate the sending party's
IP address with the defined public IP address instead of the system's private IP address.
When the remote IP device sends VoIP packets to the defined public address, all packets
will be routed to the system's provided IP address by the NAT router.
Defining the IP Dialing Table
The IP Dialing Table is used for creating location-based VoIP routing in the enterprise. It
supports H.323 and SIP dual protocol.
To use an AltiWare-to-AltiWare connection for VoIP, you need to configure the routing
in the IP Dialing Table for each AltiWare system.
Notes
• The IP Dialing Table is disabled unless there is a VoIP board installed.
• You must assign an IP Trunk Access code (System Configuration > Number Plan
tab).
• You must set the VoIP codec profiles.
To manage the IP dialing table, click the IP Dialing Table tab in AltiEnterprise Manager:
