Configuring AastraLink Pro 160 System and Network Parameters

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 

 in the 

Boston office, you would dial 

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.

The parameters you can specify for AastraLink trunking are:

Specifies the IP address or FQDN of the remote AastraLink.

Specifies the user name (a simple number string) that you use to access the 
trunk. For example, 100. 

Specifies the port number of the remote AastraLink on which 
communications are received. By default this is set to 4569.

When you configure AastraLink Pro 160 trunks, note the following guidelines:

•

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

•

You must assign the same user name to each end of the trunk.

•

AastraLink IP phone network can have the same, or different, dialing plans.
