INE Needs to update Cisco Voice Training.
Version 8/8.5 was quite a while ago now and the voice/collab training has many good fundamentals and relevant topics, but much is needed in the delivery and deployment of a true CUCM deployment with Spark, possibly cross-breeding with Skype for Business. These are the relevant solutions being deployed today at least update to 10.5 and ASR router tech is needed. Theory is great but design build and deploy real world models. Not everything is about the initials behind a name.
