[Asterisk-Users] Detecting Fax and bad CDRs

    This was an option. Until you consider that if I have 1000 customers who
all need a seperate fax did that I now have to get and manage another 1000
dids

    You're exactly right. Not only that, but if the call is "Answer'd()" by
asterisk, the disposition becomes 'ANSWERED' in the cdr AND I now have
billable seconds.

    This is bad 'cause if someone calls a customer and hangs up before VM
picks up, the call was Answered, the CDR shows billable time and therefore
CDR will tell my customer the call was answered, instead of "missed" and I
bill them for that.

    Is there any way to change the CDR info after the callee has hung up?
