Last week Light Reading/Unstrung held a webinar on Voice
over LTE.
The featured speaker was Franz Seiser, head of core network architectures for T-Mobile (now Deutsche Telekom).
It was very informative. I definitely recommend listening to the replay available here.
Franz covered drivers for VoLGA, problems with CS Fallback, and the critical need for SMS support in data-only LTE deployments.
