At the risk of not being thorough enough and then being corrected!


Jess, information indicator digits are made available when using a t-1
with feature group d like setup or on  a PRI also setup like a Feature
group D.  I say like only because in most circumstances here in the US
II's are not part of the original setup and you have to request to have
them added by the carrier.  In PRI, with an ATT switch they are
generally made available through the use of Codeset 6 and are pre-pended
to the ANI of the calling party.  If MF separated by KP ST or DTMF
delivery then separated by asterisk sign.  

Hope this helps!
