문제
I am trying to detect caller id information from telephone line. The caller-id information received is in DTMF tones (not FSK). How can I detect this DTMF tones ? Is Phone and Fax Modem capable of it ? The Phone and Fax Modem is capable of detecting FSK information, but not DTMF information.
Notes: I am using C# language and .NET as developing platform.
