6. Appendix I – Dial Plan Administration:
6.1.1. Dial Plan
The SPA-2000 allows each line to be configured with a distinct dial plan. The dial plan specifies how
to interpret digit sequences dialed by the user, and how to convert those sequences into an outbound
dial string.
The SPA-2000 syntax for the dial plan closely resembles the corresponding syntax specified by
MGCP and MEGACO. Some extensions are added that are useful in an end-point.
The dial plan functionality is regulated by the following configurable parameters:
• Interdigit_Long_Timer
• Interdigit_Short_Timer
• Dial_Plan ([1] and [2])
Other timers are configurable via parameters, but do not directly pertain to the dial plan itself. They
are discussed elsewhere in this document.
Interdigit Long Timer:
ParName: Interdigit_Long_Timer
Default: 10
The Interdigit_Long_Timer specifies the default maximum time (in seconds) allowed between dialed
digits, when no candidate digit sequence is as yet complete (see discussion of Dial_Plan parameter
for an explanation of candidate digit sequences).
Interdigit Short Timer:
ParName: Interdigit_Short_Timer
Default: 3
The Interdigit_Short_Timer specifies the default maximum time (in seconds) allowed between dialed
digits, when at least one candidate digit sequence is complete as dialed (see discussion of Dial_Plan
parameter for an explanation of candidate digit sequences).
Dial Plan[1] and Dial Plan[2]:
ParName: Dial_Plan[1] and Dial_Plan[2]
Default: ( *xx | [3469]11|0|00|<:1408>[2-9]xxxxxx |
1[2-9]xx[2-9]xxxxxx | 011x. )
The Dial_Plan parameters contain the actual dial plan scripts for each of lines 1 and 2.
