Custom port + TLS + self-signed certificate

[lgg]

Some other SIP clients(Bria/GroundWire/MicroSIP) works fine with server.

Does Telephone support TLS + self-signed certificate on custom port(e.g. 34000)?

Bump for the win. I've tried just by curious to add ;transport=tls into my proxy settings and now everytime it loads up it crashes at the same time. I guess tls is not supported, which is a shame, i myself must agree with Igg that tls + srtp is quite mandatory nowadays. thanks

@lgg do you want to have a self-signed certificate so that the server could authenticate Telephone as a client? Or do you mean self-signed certificate for the server?

I can confirm there's still an issue with a self-signed certificate. Would be nice to have an option to bypass certificate check validation. Alternatively, there could be an option to upload keys and trusted certificates instead.

TLS is supported since version 1.5, but self-signed certificates are not yet supported.

I would also love to see this.

This is important, Sectigo CA signed TLS certificates are not supported in the latest MacOS causing this for Telephone on MacOS.

A way to import the Sectigo CA certificates would be a workaround, but Apple needs to add them to the CA certificates available to programs from the OS. The browsers bundle and include more CAs.
