Configuring AastraLink Pro 160 System and Network Parameters
Configuring Network Settings
—The AastraLink is installed behind a UPnP enabled router, but the AastraLink Pro 160 does not currently support the router model.
When this parameter is set to Disable (the default), in order for the AastraLink to support external calls, you have to:
—Manually configure the AastraLink external connection parameters (see page
—Manually configure the equivalent port forwarding on the Internet gateway/router so that the AastraLink is reachable from IP phones and SIP trunks outside the LAN.
•External Gateway IP
Specifies the IP Address of the external gateway/router that the AastraLink uses to communicate with the remote IP phones. If you enable UPnP support, then the AastraLink automatically populates this field. If UPnP is not enabled but remote office is enabled, you must manually enter the IP address, FQDN or DNS hostname of the public network.
•HTTP Port Start
Specifies the public network HTTP port on the router that the AastraLink uses to communicate with the remote IP phones. Default is 51510.
This port must be forwarded to port 9600 on the AastraLink from the public/external side of the Internet gateway/router. Doing so allows remote office IP phone users to connect to the AastraLink device and the local phone network.
Note that for security reasons, remote IP phone users cannot directly access the AastraLink Web UI using port 9600. Thus, remote IP phone users must use the IP phone UI for all operations.
If UPnP is enabled, port forwarding is attempted automatically (see the HTTP Port Range parameter).
Note: The AastraLink Pro 160 listens for remote office HTTP traffic on port 9600. If you are manually configuring
