Hi list. I was googling about this subject and found a message to this list asking the same thing I want, but see no response. So, I'm reposting it in case someone has a solution for this. I'd like to know if there's some way to "detect" (not block) a collect call in a ISDN E1? I need this cause I have my own billing system and I need to charge my customers for collect calls
