SIP Trunk Page
The SIP Trunk wizard page configures the SIP Trunk settings.
The following fields are read-only:
|
■
|
'Network Type': Displays the IP network interface for communicating with the SIP Trunk. |
|
■
|
'NAT Public IP': Displays the public IP address (of the Enterprise router) for communicating with the SIP Trunk. The field is applicable only when the device is connected to a router that performs NAT. Note that the Enterprise router must be configured to "port forward" all VoIP traffic from the SIP Trunk (located on the WAN) to the device. The exact port forwarding configuration is displayed on the Conclusion page and consists of the device's address, SIP listening port (e.g. 5060) and a range of media ports defined below (e.g. 6000-6999). |
