Configuring AastraLink Pro 160 System and Network Parameters
Configuration Guidelines
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.
• Currently, global phone directory synchronization between AastraLink Pro
160 devices is not supported. Therefore, users can access phone directories
for their local AastraLink IP phone network only.
• AastraLink trunking requires a flat network. The AastraLink devices do not
support UPnP operation through a gateway/router/firewall.
• Before you use the Web UI to configure AastraLink trunks, we strongly
recommend that you do the following:
— Assign an access digit to each AastraLink Pro 160 device in your
network.
— Make a list of the trunks you want to configure.
— Identify the user name for each trunk you are configuring.
AastraLink Trunking Example
For example, suppose the system administrator wants to configure three trunks:
• Atlanta/Boston
• Atlanta/Chicago
• Boston/Chicago
The administrator begins by assigning access digits to each of the AastraLink Pro
160 devices, as shown in the table below:
AastraLink Pro 160 IP address Access Digit
Atlanta 10.30.50.125 0
Boston 10.30.60.135 1
Chicago 10.30.70.145 2
