3.2.1 VoIP Advanced
(partial screen shown)
Preferred Compression Type: Use the
setting you were given, otherwise leave the
default.
NAT routers may interfere with your VoIP calls
so you may need to do one of the following.
• If you were told to use STUN or an out-
bound proxy server, select the Active
check box and enter the provided server
address and port information.
• Alternatively, select the Active check box
in the Use NAT section and type a NAT
router's public IP address and SIP port
number. You must also configure the NAT
router to forward traffic with this port num-
ber to the Prestige.
Click Apply.
Note: The PWR/VoIP LED turns orange after the Prestige registers your SIP account.
