Verizon hopes to avoid any handoffs to CDMA when it deploys VoLTE. It hopes to have its LTE footprint big enough, which I believe is one of the reasons why it keeps pushing VoLTE deployment out--that an a whole lot of technical issues to get VoLTE on the same quality level as circuit switched.
Yeah, handoff will hopefully be a short-term problem, but I was surpised to hear all the testing vendors say how bad it is right now. I haven't used an LTE phone enough to see for myself, but if the process is anything like cellular to Wi-Fi, that'd be pretty painful.
