Doorbird and Certificates

For anyone who has Doorbird installed at home (or in business environment, but I mostly want to assume the home environment), I want to know if Doorbird supports certificates such as an input for certificate authority, certificate, and private key.

In News360, I came across an article about Ring’s security.

I want to make use of Doorbird for Asterisk PBX in the near future, as I currently do not have Doorbird at the time of writing. I only want to store the data in my home network and I cannot trust the security of Ring doorbell, so does Doorbird support certificates for SIP?
