Configuring NAT
Note: This section is only for an IP 705 phone that is using an H.323
version of AltiGen phone firmware.
NAT (Network Address Translation) is the translation of an IP address
used within one network to a different IP address known within another
network. One network is designated as the inside network, the other is the
outside. The IP 705 can be enabled to support H.323 behind NAT. The IP
705 will be able to work behind a regular NAT router without any special
implementation for H.323.
Note: If more than one IP 705 phone sits behind NAT, a VPN tunnel is
required to connect between the NAT router and the corporate
router.
Enabling NAT
By default, NAT is not enabled. If you connect the IP 705 behind a NAT
router, you must enable NAT.
To enable NAT,
1. Press the Menu button.
2. Use the button to scroll to NETWORK, then press the Enter button.
3. Scroll to ENABLE NAT, and press Enter.
