Configuring Near-End Nat Traversal For Ip Gateway Trunks - Inter-Tel AXXESS Manual

10.9 If the "Auto" NAT Type is designated for an IP endpoint in DB Programming, the Auto
NAT Detection feature determines the correct IP address to use when the endpoint comes
online. After the NAT type is determined, the IP endpoint uses the setting for all calls. How-
ever, the NAT IP address associated with the system must be programmed manually in order
for the NAT detection test to run.
10.10 Auto NAT Detection supports the following endpoints:
•
Models 8600, 8620, 8622, 8662, and 8690 in ITP mode
•
Model 8660
•
Axxess/Eclipse IP PhonePlus
•
IP SLA
•
Model 8602 IP softphone
Auto NAT Detection does not support the following endpoints. The NAT setting must be set
manually for:
•
Inter-Tel IP endpoints in SIP mode
•
Inter-Tel wireless IP endpoint Models 8664, 8665, and 8668
•
Model 8601 SoftPhone for Pocket PC
•
IP gateway trunks
•
Non-Inter-Tel SIP phones

11. CONFIGURING NEAR-END NAT TRAVERSAL FOR IP GATEWAY TRUNKS

11.1 In addition to IP endpoints, the Axxess system also supports near-end NAT traversal for
IP trunk gateways. Note that IP trunk gateways impose additional restrictions on far-end NAT.
11.2 To configure near-end NAT traversal for IP Gateway trunks:
Configure the static NAT assignments and the IPRC NAT IP Address assignments as
1.
described in step 1 on
notes.
In System\Devices and Feature Codes\Trunks, set the NAT Address Type to
2.
MGCP Gateway and SIP Trunk gateway.
Repeat this process for each IP gateway trunk.
