8.2 Telephone Calls
To make a call, simply dial the number. The dial plan (i.e. the dialed digits) is
normally customized for each installation. The default dial plan allows for dialing of
4-digit extensions or direct IP addresses. Shorter extension numbers (e.g. 3-digits)
can be dialed by completing the dial string with a final #.
When a Call Server (SIP Proxy Server) is configured into the system, the dialed
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 dialed-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).
