B.3 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:
• If the input was dragged or selected, then the entire input is compared to each dial plan. If a complete match
is found, then that account is selected and the associated transformation is performed. If no match is found,
the default account is selected and no transformation is performed.
• If you are typing the input, the digits are compared one by one as they are entered. The comparison will
result in one of the types of matches 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.
Results of the Comparison
Bria finds a match according to the following rules. These rules work on three elements:
• The patterns specified in the dial plan.
• The T timer, if it is included in the pattern.This timer is a short (critical) timer. T timer is 4 seconds.
• The long timer, which is always effective (it does not have to be included in the pattern). The long timer is
20 seconds.
Type of Match Conditions
Result if You Press
Enter or Dial
Result if You Stop Typing
Partial match The characters typed so far follow the pattern but
there are not yet enough characters for a pending
or complete match. The default account is
selected. No transformation
is performed. If you stop typing for the long
timer length (20 seconds), then
the default account is selected.
No transformation is
performed on the characters
typed so far.
Pending match • The pattern has no . (dot) but does have the T
timer. There is a perfect match.
• The pattern has a . (dot) and the T timer. The
minimum requirements are met.
This pattern's account is
selected and the
transformation is
performed.
If the T timer expires, this
pattern's account is selected
and the transformation is
performed.
Complete match • The pattern has no . (dot) and no T timer.
There is a perfect match.
• The pattern has a . (dot) but does not have the
T timer. The minimum requirements are met.
This pattern's account is
selected and the associated
transformation is
performed.
This pattern's account is
selected and the associated
transformation is performed.
No match The characters typed do not match the patterns
for any dial plan. The default account is
selected and no
transformation is
performed.
Nothing happens even after the
T timer and long timer have
expired.
