Version 6.4  309  March 2012 
SIP User's Manual   18. GW and IP to IP 
The MF KP, ST, and STP digits are mapped as follows:  
  * for KP 
  # for ST 
  B for STP 
For example, if ANI and PANI are received, the SIP INVITE contains the following From 
header: 
 
From: <sip:*nnnnnnnnnnnn#*mmmmmmmmmm#@10.2.3.4>;tag=1c14 
 
Note:  It is possible to remove the * and # characters, using the device's number 
manipulation rules. 
 
If the device receives the SIP INFO message below, it then generates a "hookflash" mid-
call Wink signal:
