in a healthcare office, client call in & they use *67 to hide their phone number. when agent suspected something bad,after hangup they dial *57 (phone provider sniffer). so the phone provider have the phone number logged in and they can call the police to give the address. it's working over a PRI.
question: over a T1 card, the phone provider need the channel ID for this call & and phone number. do you know how to programm it?
tought one..
thanks
