Keep SIP websocket connection alive accross all HA pages

[nanosonde]

Hi!
Being not a web developer I wonder if it possible to load some JS module (defined under "resources") with every lovelace page?
I read something about service workers and the like. However, I am not sure if this would be the correct way to do it.

Basically I would like to have the SIP UA registered on all HA web pages.

Good idea, would be awesome to get a popup from a incoming call while in another page.

Maybe we could do this. As long as it is client side javascript it should be possible.
But it would need to get the card config or some other global config.

But I'm not gonna give this much priority myself, I'm trying to get everything solid and polished for release. Will try it later after release.
