Hi Jan,

The Clearwater I-CSCF and S-CSCF (that is, Sprout, Homestead and optionally 
Ralf for Rf) are capable of supporting a VoLTE to VoLTE call. However:

  *   Bono isn't a fully featured P-CSCF, and so isn't suitable for VoLTE 
environments (as you note, it has no Rx interface, and also no IMS AKA or IPSec 
support). We've tested with Metaswitch's commercial Perimeta product - 
http://www.metaswitch.com/products/perimeta-session-border-controller.
  *   You can't provision subscribers with IMS AKA authentication through 
Ellis, so you'll need an external HSS. We've tested with the OpenIMSCore HSS 
(http://openimscore.sourceforge.net/), which is open-source, free, and does 
support IMS AKA.

Best,

Rob

Subject: [Clearwater] No RX interface

Hi all,


I am very interested to know if Clearwater supports basic VoLTE to VoLTE call 
and how it is achievable since it does not have any Rx interface towards PCRF ?


Thank you
Jan
