SIP-3-BADPAIR: Unexpected event 16

[penn]

I keep seeing this message in the log of my 3640 sip gateway. I can't figure out what it means or what, if anything, I can or should do about it:

Nov 14 14:19:35 CDT: %SIP-3-BADPAIR: Unexpected event 16 (SIPSPI_EV_CC_CALL_MEDI

A_CHANGED) in state 11 (STATE_RECD_INVITE) substate 0 (SUBSTATE_NONE)

Does anyone know what this means?

The problem may be due to

CSCsb72851, which is resolved in 12.4(3b) and it shouldn't have any impact on calls.

Thanks!
