Codes
These codes tell the ATA what to do when the user places
the current call on hold and is listening to the second dial
tone.
One or more *codes can be configured into this parameter,
such as *98, or *97|*98|*123, etc. The maximum length is
79 characters. This parameter applies when the user
places the current call on hold by pressing the hook flash
button. Each *code (and the following valid target number
according to current dial plan) triggers the ATA to perform
a blind transfer to a target number that is prepended by
the service *code.
For example, after the user dials *98, the ATA plays a
special dial tone called the Prompt Tone while waiting for
the user the enter a target number (which is checked
according to dial plan as in normal dialing). When a
complete number is entered, the ATA sends a SIP INVITE
message with the Refer-To target equals to *98
target_number.This feature allows the ATA to hand off a
call to an application server to perform further processing,
such as call park.
The *codes should not conflict with any of the other
vertical service codes internally processed by the ATA.
You can empty the corresponding *code that you do not
want the ATA to process.
