Figure 27 NAT Traversal Configuration
Table 13 NAT Traversal Configuration
LABEL | DESCRIPTION |
|
|
Select Type | Select None if the Prestige is not behind a NAT router or the NAT router is a SIP |
| ALG. |
| Select By Outbound Proxy if your VoIP service provider has a SIP outbound |
| server to handle voice calls. This allows the Prestige to work with any type of NAT |
| router. Turn off a SIP ALG on a NAT router in front of the Prestige to keep it from |
| retranslating the IP address (since this is already handled by the outbound proxy |
| server). |
| Select STUN if there is a NAT router between the Prestige and the VoIP service |
| provider’s SIP server and your VoIP service provider hosts a STUN server. |
| Select Fake WAN Address on SIP and RTP to use a NAT router’s public IP |
| address and SIP port number in the Prestige’s SIP messages. You must also |
| configure the NAT router to forward traffic with this port number to the Prestige. |
