Special Characters Used When Writing Dialling
Instructions
These characters perform special functions:
& – This is a hook-flash which is critical for signalling on analogue systems.
, – The comma is a 1-second pause.
T – Tells the port to switch to tone (DTMF) dialling. This is the default.
W – Wait for answer. On encountering this character, SVM will monitor the
line for an answer from the called station before dialling any additional charac-
ters. If no answer is detected, the call will fail.
; – The semicolon is 'wait for dial tone'. The SVM will wait up to 12 seconds
for dial tone before dialling any additional characters. If no dial tone is detect-
ed the call will fail. This is useful in environments that may have a shortage of
resources such as a limited number of trunk lines or DTMF receivers.
$K – Stands for 'key value' and causes the SVM to insert the ID number of the
last Extension Block, Mailbox Block, or Menu Block input into a dial string.
