UNSOLVED Video conferencing module (like Skype)

[HBommert]

we need module, which acts like skype.
Reason:
I am an instructor in a social organization for people with special needs.
Actually we are building smart mirrors for the boarding schools and the assisted living homes.

Our special need for our smart mirror project is a kind of video call functionality (like Skype) for the deaf people.

They should be able to get in touch with the person on charge in the night if their is an emergency situation. Telephone is not a solution, because the deaf people need to see the person in charge and gesticulate with him.

So the module should be able to get in contact with a cellphone or a computer. The mirror will have a cam installed.
