Is there a video call software on linux that I can use in the following manner :
User A calls User B. User B has a specific userID / number / Identifier / ... that User A uses.
The software in User B 's side sees the userID / number / Identifier / ... of User A. Then it automatically redirects the call to User C, using User C -s userID / number / Identifier / ...
If User D calls User B, then the call is again redirected to User E.
So, what I am looking for is a rudimentary call redirection (or routing, as mentioned in comment below) functionality.
Is there something like that available? Thank you.
