This is a decent article on some of the underlying standards: http://www.radio-electronics.com/articles/cellular-telecoms/current-volte-development-and-deployment-29 http://www.radio-electronics.com/articles/cellular-telecoms/... I worked on an implementation of an IPSEC VPN using SIM auth for IMS. GSM standards are amazing in how they make everything work together across many different generations.
- smikhanov 11y agoWas it really "SIM auth for IMS" or is there a typo and it's "SIP auth for IMS"? Sounds like an interesting project you did.
