hi all, i read a post on this group...i want to detect caller id on my telephone line and i thought that using the MT 8870 was a good idea so i got hold of the circuit and the datasheet .but i was unable to detect caller id on my telephone...i counld detect a single digit. can anyone tell me if there are certain requirements for this ic to work? (like the incoming signal should only be dtmf and not modulated or something of the sort..) any help will be most welcome...Anand Dixit. p.s. : are there any ic that detect FSK based caller id??? or convert the FSK signal to some other data format???
