[Asterisk-Users] outbound caller ID problem on PRI

[CW_ASN - Gus]

Alastair:

At least in some European countries and southamerican environments, you
can't send your own ANI.
For example: if you have a PRI with the number: 52880000 to 52880099, you
could send as ANI any number between 000 and 099. The fixed part will be
transmitted by your PSTN switch to the network attaching the last 2 number
that you send. Generally, if you send a differente qty of numbers that the
switch needs, the ANI transmited by the PSTN switch will be the DID number
(generally, 52880000).
If you could send you own ANI, the carriers will be charge the calls to that
ANI... think about it. It's a fraude principle.

You could set "Presentation Indicator" in setup message. If you set to
"Allow" your ANI will be shown in the other side, and if you set as "Not
allow" the PSTN will hide your ANI. This is valid only to show the data in
the B subscriber FSK demodulator (callerid receiver).

Regards,

Gus
