Dual-tone multi-frequency (DTMF) signaling is still in widespread use.
Use this program to signal and testing of DTMF, to enable DTMF to older phones or to open a Echolink repeater. Just hold the mic in front of the PC speakers and push the buttons.

of malware, spyware, viruses, trojans, etc. We will re-test each updated
