[asterisk-users] J1/INS1500 and the Redirect Number

[Gary Mensenares]

Hi everyone!

I'm wondering if anyone on the list had the opportunity to work with an NTT
INS1500 ISDN PRI service before.

You see, in Japan, if you receive a call that was just forwarded by another
number, the call presentation not only includes the caller (ANI) and your
number (DNIS), it will also usually include the forwarding number
(REDIRECT). Does anybody know how to extract this field on Asterisk?

For reference, you can look at
http://www.ntt-east.co.jp/ISDN/tech/spec/espec/3-5/content_3.html. This is
the full specification of INS 1500 signalling. Any assistance would be very
much appreciated.

Thanks again!

Sincerely,

Jug Mensenares
