Can anyone suggest a suitable DAA to be used with MT8880/ CM8880. Philips TEA1062A works with HT9200 dialer but not with MT8880 / mt8888. a dial genarates the correct DTMF frequencies and I am able to hear the confidence tone also in the earpiece. But the remote telephone does not ring. But wit HT9200 it rings. What could be the likely fault? I am making a dialer with call progress detection.
Thanks in advance foryour time.
