• CUBE anti-tromboning does not work when one call leg uses media flow-through and the other uses media flow-around. in context
• Cisco documents media anti-tromboning as a CUBE media path mode that detects media loops created by call transfers or forwards and removes them from the RTP path, leaving the loop only in SIP signalling. in context
• CUBE anti-tromboning does not work when one call leg uses SDP pass-through and the other uses normal SDP handling. in context
• The CUBE guide for IOS XE 17.6 onwards says anti-tromboning is possible for SRTP calls, but only when SDP pass-through is enabled. disputed in context
