Possible to be notified from Dahua intercom to Amazon Echo, talk two way and open the door?

Hi, much stuff is involved here, get noticed by intercom by CGI commands I don't know if possible, notify Alexa about the incoming call is possible I've read, establish a two way audio can be possible by SIP? I guess.. then open the gate it's easy by CGI. What is your opinion? Thanks

Hi Giovanni,

I do something similar on my voip intercom that when its dialled it turns on the lights on the driveway
If you can get the intercom to access a url you could get it to access a cgi-bin script that issues a MQTT command which node-red could then send a notification to alexa.
Keep in mind, you'd need a webserver installed with cgi-bin configured

#!/usr/bin/python
import time
import sys
import os
import datetime
import subprocess


os.system("/usr/bin/mosquitto_pub -h localhost -t phonedial  -m ON")

as far as audio/SIP, I don't believe this is possible
