Hello,

I am using baresip in a context where multiple people are connected to the same SIP account. Invites are sent to all registered devices and if one device picks up, the other devices receive a Cancel with a Reason line like this: Reason: SIP;cause=200;text="Call completed elsewhere"

It would be really nice if the menu could show this in a nice way. The event handler should have the necessary information in the char *prm variable if I read the code correctly.

This way the other people connected to that SIP account know that they do not need to call the person back if the call was accepted elsewhere instead of being missed by everyone.

I'd be willing to make a PR but I wanted to see if you have thoughts on how to display this nicely as I am more of a backend dev and not that familiar with UI considerations, I'm also not sure if any other parts like a call history could/should be affected by this.
