Toggles the line to a fax machine.
The default is #99.
Use for media loopback.
The default is *03.
These codes tell the SRP what to do when the user
places the current call on hold and is listening to the
second dial tone.
One or more *code can be configured into this
parameter, such as *98, or *97|*98|*123, etc. Max total
length is 79 chars. This parameter applies when the
user places the current call on hold (by Hook Flash) and
is listening to second dial tone. Each *code (and the
following valid target number according to current dial
plan) entered on the second dial-tone triggers the SRP
to perform a blind transfer to a target number that is
prepended by the service *code.
For example, after the user dials *98, the SRP 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 SRP sends a blind
REFER to the holding party with the Refer-To target
equals to *98 target_number. This feature allows the
SRP 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 SRP.
You can empty the corresponding *code that you do not
want the SRP to process.
