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
```auto
#!/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

thank you a lot, this is cool 🙂
So I need to setup a cgi server, and ask intercom to notify there a call coming, is it right? Should it be done each time the intercome reboots?
May you please explain a bit better waht about MQTT? If you can briefly describe the steps that has to be taken, thank you a lot!
