How the Input Is Processed
Comparing Input to the Dial Plan Patterns
The input is compared to each dial plan in turn, starting with the first listed account. The process is slightly
different depending on how the call is placed, as described in the table below.
It is possible for the same input to get matched to different dial plans depending on whether the input is entered
on the fly or dragged. It is important to keep this in mind when designing dial plan patterns.
Keyword Description
prestrip Strip the first n characters from the input before placing the call.
poststrip Remove n number of characters from the end of the input before placing the call.
pre Add the specified prefix to the input before placing the call.
post Attach the specified postfix to the input before placing the call.
replace Replaces the input with the specified string before placing the call.
