AastraLink Pro 160 Administrator Guide
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:
dial prefix Boston = 7 + 1 + (number)
If you are located in the Atlanta office, and you want to reach extension 200 in the
Boston office, you would dial 71200 .
Note: Calls between AastraLink systems support NAT traversal for IAX
(AastraLink trunk) calls when used with either a supported UPnP router or
with manual port-forwarding.
For networked systems, using 8-prefix AastraLink trunk dialing between
sites, the barred number list is also applied locally on each AastraLink Pro
for incoming dialed numbers. This allows flexible and secure provisioning
rules to be enforced for toll-bypass (i.e. local PSTN breakout) as if the
remote system had dialed the number directly from the local system.
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.
