• Referral Services Codes: One or more * code can b* codee configured into this parameter,
such as *98, or *97|*98|*123, and so on. The maximum total length is 79 characters.
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 SPA9x2 to perform a blind
transfer to a target number that is prepended by the service * code.
For example:
a. After the user dials *98, the SPA9x2 plays a special prompt tone while waiting for the
user the enter a target number (which is validated according to the dial plan as in
normal dialing).
b. When a complete number is entered, the SPA9x2 sends a blind REFER to the holding
party with the Refer-To target equals to *98 target_number. This feature allows the
SPA9x2 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 SPA9x2. You can empty the any * code that you do not want to SPA9x2 to
process.
• Feature Dial Services Codes: Tell the SPA9x2 what to do when the user is listening to the first
or second dial tone.
You can configure one or more * codes into this parameter, such as *72, or *72|*74|*67|*82,
and so on. The maximum total length is 79 characters.
When the user has a dial tone (first or second dial tone), they can enter a * code (and the
following target number according to current dial plan) to trigger the SPA9x2 to call the
target number prepended by the * code.
For example:
a. After the user dials *72, the SPA9x2 plays a special prompt tone while waiting for the
user the enter a target number (which is validated according to the dial plan as in
normal dialing).
b. When a complete number is entered, the SPA9x2 sends an INVITE to *72 target_number
as in a normal call. This feature allows the proxy to process features such as call forward
(*72) or BLock Caller ID (*67).
The * codes should not conflict with any of the other vertical service codes internally
processed by the SPA9x2. You can empty any * code you do not want to SPA9x2 to process.
You can add a parameter to each * code in Features Dial Services Codes to indicate what tone
to play after the * code is entered, such as *72‘c‘|*67‘p‘.
Following is a list of allowed dial tone parameters (note the use of back quotes surrounding
the parameter without spaces).
