%SIP-3-BADPAIR:

[knmezi]

Please can anyone explain this error message and what caused it. I see whenever I made an inbound call:

pr 15 11:31:09.565: %SIP-3-BADPAIR: Unexpected event 16 (SIPSPI_EV_CC_CALL_MED

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

Also how I can fix it.

Knmezi.

The SIP state machine has encountered an error while processing an event or timer.

We opened TAC case on this problem earlier this month with Cisco, we were told that ios release 12.4.5 will fix this issue. I think this release is due some time in feb.
