This repository is not an official Signal Guide and there is no relation to the team behind Signal. It's just a guide written outside my work-time to help people.

Q: Will I be able to do ... with Signal?
A: My suggestion is first you need to setup normal signal server and check if it will fulfill your need.
Q: My chat only goes one way or can't send chat even when the server already set properly.
A: Probably caused by keystore haven't contain your SSL certificate / certificate did not match the url / you have not setup the Unidentified Delivery properly in the client. Will be explained in each guide of the server & clients.
Q: How to setup Turn Server? I can't do voice/video call.
A: Probably related to your port, either it is not allowed by the firewall or it is not properly set. See my example config on Coturn Server
Q: Can I subtitute AWS to MinIO?
A: I tried it here signal-minio using modification created by kondal789rao . Someone also did a pull request here: Use MinIO instead of the AWS. Also you can try to look into Localstack for local development.
Q: Can I disable / change Twilio? (by getting the generated OTP on the server)
A: Yes, it is possible, you need to change TwilioSmsSender Class, see example on Signal Server Without Twilio.
Q: Can I use Signal in localhost / internal IP / self-signed certificate (by trusting all certificate)
A: Yes, it is possible but it is not secure, see example on Signal Server Self Signed Certificate.
Q: Can I remove Google Mobile Service (GMS) from Signal?
A: Yes! A Signal user named "tx-hw" did it on their Github Fork of Signal-Android. You can read more about it on their Signal Community Post
