Hi,
I want to dial telephone using MT 8888c DTMF, but when I use burst mode (50ms send - 50ms stop), the PABX didn't responded.Seem the PABX doesn't support burst mode.
So, I disabled the burst mode and IRQ, and made delay 100ms send -100ms stop, but the MT8888c only succeed send 100ms DTMF 1 times after that the DTMF send 50ms again and again. I change the program, so every time send a number, I have to initialize the MT8888c and gave 100ms delay on and off.
After that, the PABX can gave ringing tone, but why the telephone number that I call is always wrong ? What is the problem ?
