AastraLink Pro 160 Administrator Guide
— 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 4-28 ), and
— 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 port-forwarding parameters for
HTTP, use
HTTP Port Start as the external port being forwarded to port
9600 on the AastraLink Pro 160.
