Description Parameter
These codes tell the IP phone 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,
and so on. 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 phone to perform a blind transfer to a target number that
is prepended by the service *code.
For example, after the user dials *98, the IP phone 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
phone sends a blind REFER to the holding party with the Refer-To target equals to
*98<target_number>. This feature allows the phone 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 IP phone. You can empty the corresponding *code that you do not
want to the phone to process.
