Set Auto Prefix
This feature allows you to define a prefix 
number to be added to the beginning of 
a number during predialling (see 
“Predialling” on page 17). You can also 
use this feature to add a detect string to 
match and replace the first few digits of 
the number during predialling. 
You can enter up to a maximum of 5 
digits for the detect string and 14 digits 
for the auto prefix number.
Note
The use of your ID555 cannot be 
guaranteed with all types of PABX.
