I would like to understand why you recommend CSipSimple.  I had trouble
with it when using ostel.co.  I am fuzzy on the details, but I think it
would start using CPU time after there was a cell->wifi handover or the
reverse and not recover.    But more seriously it appears to have no
functioning upstream, and the last release was in 2014.

I have used linphone instead, which seems maintained.  However the most
recent version is not yet available on f-droid.

I gather Ring can do regular SIP too.


Another question is that your system seems to do SMS over xmpp, and PSTN
phone via SIP.  But I also see a sip-like service used over xmpp some
times (jingle?).  I am curious about your rationale for which one to use
(and guessing standards compliance and interoperability).
