I am trying to build an auto dialer and I am using Philips TEA1062 DAA and MT8880. I am seeing the correct DTMF tones being generated and I also hear the confidence tone in the earpiece. However the remote telephone never rings? What is the likely problem. Iam able to use the same interface and create rings with Holtek HT9200 dialer. I switched to MT8880 as it also has a DTMF decoder and CPTD.
Thanks in advance for your time and help
