Description (partial)

In certain scenarios, CUCM may send two crypto lines in an ACK w/ SDP.  When this defect was discovered, there was no crypto match for the call and SRTP fallback was disabled, so this call would have failed either way, but CUCM shouldn't be sending two crypto lines, neither of which were compatible with CUBE.
