Configuration Parameters; Configuration Guidelines - Aastra AastraLink Pro 160 Administrator's Manual

When you enable AastraLink trunking, you assign a unique access digit to each
AastraLink device in your network. For example, suppose you assign the access
digit 1 to the AastraLink in the Boston office. Then, the dial prefix for the Boston
office is as follows:
If you are located in the Atlanta office, and you want to reach extension
Boston office, you would dial
Note: Calls between AastraLink systems require a flat network topology, and do not support
UPnP / static port-forwarding. (For example, the trunks do not work through NAT firewall
connections).
Connections between sites should be done using either VPN routing or wide-area direct routing so
that the AastraLink to AastraLink trunk connections do not traverse a network address translation
boundary.

Configuration Parameters

The parameters you can specify for AastraLink trunking are:
• Hostname
Specifies the IP address or FQDN of the remote AastraLink.
• Username
Specifies the user name (a simple number string) that you use to access the
trunk. For example, 100.
• Port
Specifies the port number of the remote AastraLink on which
communications are received. By default this is set to 4569.

• You can configure a maximum of 10 AastraLink trunks and user names on a
single AastraLink Pro 160 device.
