5.2 Telephone Calls
To make a call, simply dial the number. The dial plan (i.e. the dialled digits) is normally customized for each installation. The default dial plan
allows for dialling of 4-digit extensions or direct IP addresses. Shorter extension numbers (e.g. 3-digits) can be dialled by completing the
dial string with a final #.
When a Call Server (SIP Proxy Server) is configured into the system, the dialled digits are translated and routed by the Call Server to the
correct destination as registered with the Call Server.
If no Call Server is configured, calls can still be made using 4-digit extensions, rather than using full IP addresses. The originator translates
the dialled-digits to a destination device as follows:
First Digit: Line identifier (for multi-line gateways)
Remaining digits: Host number part of an IP address. The Network number part is considered to be the same
as the caller’s IP address.
For example, if a caller at address 10.136.64.33/24 dials “2023”, the call will be placed to the second line at address 10.136.64.23. All
devices have to be on the same Class C subnet (24-bit subnet mask).
To dial an IP address directly, dial the IP address digits using * on the keypad as the dot. Complete the address with a final * or #. When
using IP address dialling it is not possible to specify which line at a gateway is called, so the gateway always routes IP-address dialled calls
to the first line.
Network busy tone (fast busy) will be played for unknown or unreachable destinations. To answer a call, pick up the phone or press the
hands free button.
