The first method is by statically configuring a trunk's InboundCallRoute. A rule can be added to the
InboundCallRoute parameter to have the AA call back the caller's or any other number, if the caller
hangs up before the AA answers. The rule should indicate that “aa(
callback-number
)” is the target
destination of the call, where
callback-number
is the number that the AA should call back if the caller
hangs up before the AA answers the call. For example, the following rule
{(<**1>(14089913313|12121559801)):aa($1)}
says that if 14089913313 or 12121559801 calls, the call is routed to AA. If the caller hangs up
before the AA answers, AA calls the number represented by $1. Recall that $1 is expanded into
the caller number after processing by the digit map on the left side of the colon. In this case, it
is the caller's number prepended by **1. The **1 is required for outbound call routing when AA
calls back; here it indicates SP1 is to be used for calling back (assuming default value of the AA
OutboundCallRoute parameter).
The
AA Service
::CallbackAnswerDelay parameter controls the number of milliseconds before AA
answers when a callback number is specified. The default value is 10000 ms (10 seconds). Without
the (
callback-number
) argument, the AA behaves the normal way and the answer delay is governed
by the
AA Service
::AnswerDelay parameter.
The second method is by selecting AA option 3 to “Enter a callback number” after the AA answers
the call. The caller can explicitly enter the number to be called back by the AA. If a valid number
is entered, AA says “Thank You” and “Goodbye”, and then starts calling back 2 seconds after the
current call has ended. If number entered is invalid, AA plays SIT tone followed by an error message.
Note that the variable $1 (representing the caller's number) is carried over to the subsequent AA
callback call. The AA DigitMap can include $1 to be used in a callback context. For example, the
following rule in the AA DigitMap
(<00:**1$1>|… )
says that if the AA dials 00, the device transforms it into the caller's number prepended by **1. In
other words, if the caller wants the AA to callback the current number (typically the case), he can
simple enter 00# after selecting option 3 on the AA menu. Note that $1 can only be used as part of
a substitution element in the digit map; it must not be used for matching elements since its value is
unknown.
User Recorded Prompts
The device supports 10 user-recordable prompts, which are referred to as the
User1
to
User10
prompts.
See the IVR Local Configuration Options on page 11 section on how they can be recorded, or the
Customized AA Prompts Backup and Restore on page 22 section on how they can be duplicated from
one device onto another device.
