Source notes citing this source

• Cisco's SRTP pass-through overview says that if the target adjacency does not support SRTP pass-through the call is rejected with 415 Unsupported Media Type, so an SRTP failure on CUBE can surface as a 415 rather than a 488. in context
• With SRTP pass-thru enabled CUBE does not support media interworking, and Cisco says incoming and outgoing dial-peers must be configured symmetrically to avoid media issues. in context
