Hello. I have my own sip install with self-signed certificate. How do I make Zoiper premium check the certificate against hash or own CA certificate?
With Zoiper for Android you cannot load your custom certificate. However it will read the CA from the android CA storage.
If your server has a self-signed certificate, Zoiper will ask you if you want to add it as an exception and approve the connection.
Does the exception pin the certificate or will it accept any certificate?
When you add the exception it will work only for this certificate. If the certificate on the server is changed you will need to add it again as an exception.
