Configuring VoIP Settings

AastraLink Trunking

You enable AastraLink trunking to support internetworking between Aastra IP phone networks. For example, if you have an office in Atlanta, in Boston and in Chicago, you can configure AastraLink trunks between the offices (Figure 4-7).

When AastraLink Pro 160 devices are networked across a LAN/WAN, IP phone users can make calls between the sites by dialing the following:

(prefix digit) + (access digit) + (extension)

Where:

prefix digit = 7 (default)

access digit = 0 - 9 (assigned by the Administrator) extension = 3 or 4 digit extension number
