Yes, that's what I meant by out-of-band proprietary thing.

Yes, and that also seems to describe an IETF approach that isn't
actually used.

Previous messages on this list have talked about using flexisip as a
proxy to deal with push, in front of asterisk which doesn't have push
support.

But, I don't know of clients that start using a proxy you didn't
configure.


There is also the notion of fixing your phone to not have doze problems,
or choosing a phone that runs an OS where you can configure things
(e.g. Lineage) and then using a client which sleeps and can still get
incoming messages.  As I understand it baresip works just fine in this
mode.  In non-SIP, Conversations (XMPP) and K-9 (IMAP) similarly work
well.
