Feature request: add trust once for phone & video calls
Context
It would be beneficial to have the option to trust phone calls once as well as to trust phone calls every time. This may become useful in the case where two people are interacting for the first time and they're not sure if they want to trust each other's phone calls, in combination with plug-ins, such as the auto answer.
Proposal
Have another button that says except call once or similar phrase next to existing except call button and change. Accept call button to always accept.
