service *code. For example, after the user
dials *98, the SPA 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 SPA sends a blind
REFER to the holding party
with the Refer-To target equals to
*98<target_number>.
This feature allows the SPA to "hand off"
a call to an application server to perform
further processing, such as call park.
Notes:
- The *codes should not conflict with any
of the other vertical service codes internally
processed by the SPA. You can empty the
corresponding *code that you do not want
to SPA to process.
Feature Dial Services Codes
One or more *code can be configured into
this parameter, such as *72, or
*72|*74|*67|*82, etc. Max total length is 79
chars. This parameter applies when the
user has a dial tone (1st or 2nd dial tone).
Enter *code (and the following target
number according to current dial plan)
entered at the dial tone triggers the SPA to
call the target number prepended by the
*code. For example, after user dials *72,
the SPA plays a prompt tone awaiting the
user to enter a valid target number. When
a complete number is entered, the SPA
sends a INVITE to *72<target_number> as
in a normal call. This feature allows the
proxy to process features like call forward
(*72) or BLock Caller ID (*67).
Notes:
- The *codes should not conflict with any
of the other vertical service codes internally
processed by the SPA. You can empty the
corresponding *code that you do not want
to SPA to process.
- You can add a paramter 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`. Below are a
list of allowed tone parameters (note the
use of back quotes surrounding the
parmeter w/o spaces)
`c` = <Cfwd Dial Tone>
`d` = <Dial Tone>
`m` = <MWI Dial Tone>
