• The CUBE IOS XE 17.6+ transcoding chapter says SCCP-based transcoding is not supported with IOS XE releases and that CUBE uses LTI instead. This appears to conflict with the IOS XE 16.12 ISR guide, which says gateway DSP media resources communicate with Unified CM over SCCP. disputed in context
• LTI-based transcoding on CUBE reaches DSP resources through an internal API. It needs no TCP socket or registration, only a DSPFARM profile associated with application type CUBE. in context
• PVDM4 modules support Opus transcoding for CUBE LTI-based transcoding. in context
