One on One: Franz Seiser Talks VoLGA

I recently had a chance to sit down with Franz Seiser, head of core network architecture for Deutsche Telekom, formerly T-Mobile International, to chat about voice and SMS over the LTE network. We discussed the evolution of LTE as it leads the industry down the path to IMS. Franz said that the industry consensus today is that IMS will be the longer-term solution, but it is still a ways off. An interim solution is necessary. Watch the video in which Franz and I briefly discuss steps and roadblocks to IMS; options for voice and SMS over LTE; and advantages for VoLGA.
