  1. I know you can’t have MTP resources with LTI, Only transcoders. I think the answer is B and D.

    Previously to use hardware (PVDM-based) transcoding you needed to register DSPFarm on CUCM or CME. But what if you don’t use any of these call control platforms, just have a router working as CUBE and want to accept one call leg and set up another with a codec different from originating? Starting with CUBE 9.0 Cisco has introduced Local Transcoding Interface (LTI) feature that permits you to register transcoding DSPFarm profile on CUBE itself.

  2. LTI is specific to CUBE. In IOS routers, specific context of this question, you must configure at least one audio codec for hardware MTP. DSP resources are also needed, I would think answers are A and D.
