Hi, I've planed to control my landline phone via my smartphone app, I've trying to use ESP8266 as wifi bridge between mobile and telephone , regards to some searching I found , I should use DTMF decoder & generator IC as well as hang up, hang down , line splitter , ID caller and line status indicator circuit in my schematic , then use Audio to digital sampler with minimum latency to deliver mobile platform , I've decided to use TCP package to control land line and UDP package to deliver voice
any advise really appreciated
