• Maximum length – Automatic sending will occur when this many digits
have been dialled.
• Timer – A shorter than normal interdigit timer to be used once the min-
imum number of digits have been dialled or when the “check” function
occurs. The timer can be zero if the two lengths are equal or with CD1.
Actually, the timer can be set to values larger than the phone’s interdigit
timer (it can be as high as 9, while the default internal timer is 6).
• Terminator – A digit used to indicate that dialling is complete before
reaching the maximum number of digits. The terminator can only be *
or #. The terminator is sent as part of the digit string.
• Option – A special function to be applied when the digits are sent. Cur-
rently two options are supported:
–
B
– Lock by-pass. Strings with this attribute can be dialled when the
phone is locked (other strings are barred by the phone).
– E – Emergency; implies B. Dialling these numbers will cancel both
forwarding and DND to allow the emergency service to return calls
to this caller. There is nothing to prevent the user re-invoking these
features later.
• Comment – although this can be left blank, it is useful to explain why
this entry is present.
Field separators depend on exactly how the dial plan is put on the phone.
Raw database entries use the separator “^”, while an external document
uses “,”.
Dial plan entries are in priority order. The phone will lock onto a matching
entry and not check later ones, except as described for the C action. It is
bad practice to have conflicting or duplicate entries as these may confuse
other investigations.
Examples of Dial Plans
Combinations of these examples can be used according to need. These
examples are deliberately short to explain specific principles.
A SIP server can be used in one of three ways. The nature of the numbers
used will vary according to the type of use – a PABX replacement, a com-
plete private network or a public exchange.
A PABX replacement in the UK might have only a few entries:
• 2,S,,4,,,B, internal numbers, can be dialled when locked
• 3,S,,4,,,B, internal numbers, can be dialled when locked
• 9,S,4,20,3,,,,external numbers
Notice that minimum lengths need not be specified at input time, however
the maximum length will be substituted internally (compare the results of
viewing “memory” and “file” on the web page with any of these exam-
ples).
A few refinements can be added, according to need:
