8.2.4.2. Configuration of the HFA users 
The HFA users (IP phones) can then be configured.
ADD-SBCSU:STNO=<stno>,OPT=OPTI,CONN=IP2,PEN=1-3-14-0,DVCFIG=OPTIIP,
COS1=33,COS2=30,LCOSV1=5,LCOSV2=1,LCOSD1=5,LCOSD2=1,DPLN=0,ITR=0, [IPPASSW=<Password>];
If a soft client has the special feature that it has TAPI 1st party
as a feature, the following AMO SBCSU configuration is required:
ADD-SBCSU:STNO=<stno>,OPT=OPTI,CONN=IP2,PEN=1-3-14-0,DVCFIG=OPTIIP&API,
COS1=33,COS2=30,LCOSV1=5,LCOSV2=1,LCOSD1=5,LCOSD2=1,DPLN=0,ITR=0, APICLASS=TSX,[IPPASSW=<Password>];
Each HFA user can be issued with their own password for the registration
which is determined by the Administrator and, similar to the PIN, cannot
be administrated by the user himself. If no password is specified, the
user call number is sufficient for the registration.
