asterisk users - Nov 2004 - Using CallingPres to set up CallerID blocking

From the Wiki:

Presentation indicator (octet 3a)

Bits
7 6 Meaning
0 0 Presentation allowed
0 1 Presentation restricted
1 0 Number not available due to interworking
1 1 Reserved


Screening indicator (octet 3a)

Bits
2 1 Meaning
0 0 User-provided, not screened
0 1 User-provided, verified and passed
1 0 User-provided, verified and failed
1 1 Network provided


How do these bits fit into "number" where CallingPres(number)?  Is
number
is binary field or a decimal field?  It is 8 bits long (the word octet sure 
seems to indicate that)?

What would number be if you wanted to block Presentation on the far end 
(when placing a call through a Q.931 PRI) if you wanted to present 
Anonymous or Unavailable?

What would number be if you wanted to present a full callerid as 
User-provided, verified, and passed?

Okay, ignore the previous question, I figured it out.


for anyone else who may also not completely grasp the wiki explanation:

number is a octet, and the only bits you need worry about are bits 1,2,6 and 7

bits 1 and 2 define the screening indicator, and bits 6 and 7 define the 
Presentation indicator.

The placement of the Bits and Meaning Header messed me up a little bit, as 
did the '(octet 3a)' as I was wondering what importance the 3a had.

So some general settings:

Presentation Allowed, Network Provided: 3 (00000011)
Presentation Restricted, User-provided, verified, and passed: 33 (00100001)
Presentation Restricted, Network Provided: 35 (00100011)
