[SR-Users] Advice on taking the best path to build a Presence & IM server

[José Seabra]

Hello Daniel,
Thank you for your feedback, it was also important receive another point of
view.

we won't follow the SIP SIMPLE path.
Right now we are looking for two options,  XMPP(Prosidy, ejabberd, etc) or
a solution based on websocktes and JSON for webrtc Apps,  itegrated with
kamailio for notifications to call states from and between physical phones
and webrtc app.

Thank you for your opinion

Best Regards
José
