For multimedia communications, a standard has been around called the Session Initiation Protocol or SIP. My sister platform, The Museum of Telephony, has explained this in a way that it’s an app-driven telephony like interface.
Originally for the fusion instant messaging or IM, video and voice calls, SIP became an international standard for basic telephony extensions (or “stacks”) for such technologies to work over the Internet. SIP is an open standard, in “theory”. As you read along, it’s going to become a cliche pretty quickly.
This isn’t telephony per se, and it gets extremely technical. And degrading men can act like fanboys of this technology too. Trigger warning! Link contains non-laymen content from an apparent misongyst!
I digress. Just bare with me.
