h_urain Posted April 14, 2004 Report Share Posted April 14, 2004 I use MT8888 to dial, but it can't work. I can hear DTMF tones by an audio amplifer but when I send DTMF tones to telephone line, it can't dial (can't make a call). Help me !!

MP Posted April 14, 2004 Report Share Posted April 14, 2004 You must send the AT command to pick up the line before the phone will dial out. Otherwise the DTMF tones are not going anywhere. Could this be the problem?MP Quote Link to comment Share on other sites More sharing options...
