Digit collection
On wink start DID trunks you will receive digits from the central office one at a time as shown
above the previous diagram. Wave keeps collecting digits until the number of digits collected
matches the number of digits in the longest Dialed Number value in the inbound routing table.
The following table illustrates a sample inbound routing table:
For example, if the inbound routing table has two values for Dialed Number, Wave will wait to
collect four digits. If Wave receives more than four digits, only the first four digits are
considered and the rest are ignored. If Wave only receives three digits, the digit collection times
out after a period, and Wave attempts to place the call with the digits it received.
Digit translation
The collected digits are compared with the steps in the inbound routing table. You can specify
a destination that uses digits in the dialed number by using x’s in the destination number. For
example, if the dialed number is 1011, and the destination for numbers matching 1xxx is 2xxx,
then the call is sent to extension 2011.
It is very important to place the steps in the order they must be considered by Wave. For
example, if Wave has an inbound routing table that contains two steps, and it receives the digits
1-0-0-0, the first step is matched and the second step is not considered.
If you reverse the steps in , the call would not go to the AutoAttendant (550). Instead, Wave
would attempt to locate extension 2000, which does not exist, and the call fails (or is routed to
the intercept destination, if one is configured).
If there is no match between the number received and the steps in the table, the number is sent,
as is, to the First Digit Table for further interpretation and routing. If the call cannot be routed,
it will be sent to the intercept destination configured in the inbound trunk group.
