5. Configure the NAT/firewall to forward TCP ports 10025, 10027, 10032, 10037, 10050, 10064, 1720 and
UDP ports 69, 5060, 10060 to MAXCS.
6. Configure the NAT router to forward to MAXCS 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 is to look in the Current Resource
Statistics window in MaxAdmin (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.
To use a MAXCS-to-MAXCS connection for VoIP, you need to configure the routing in the IP Dialing Table for
each MAXCS 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 sub-tab in Enterprise Manager:
