Codes
These codes tell the SPA9000 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 
SPA9000 to perform a blind transfer to a target number 
that is prepended by the service *code. 
For example, after the user dials *98, the SPA9000 
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 SPA9000 
sends a blind REFER to the holding party with the 
Refer-To target equals to *98<target_number>. This 
feature allows the Cisco SPA9000 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 
Cisco SPA9000. You can empty the corresponding 
*code that you do not want to Cisco SPA9000 to 
process.
