Cross-Communicate
Cross-Communication is the communication between a bunch of people in real life (at an event) and to someone or a group of people on a communication device.

It can be used in different ways such as call, video call and social media... Etc
It is used when someone is unable to attend to their friends/familys event (like a party) so they end up communicating without being there.
Friend: "Sorry I can't go to your party because parents won't let me."
Host: "Sure just cross-communicate via video call."
Friend: "Sounds like a great idea."
