Usage Guidelines
The debug voip ccapi inout EXEC command traces the execution path through the call control API,
which serves as the interface between the call session application and the underlying network-specific
software. You can use the output from this command to understand how calls are being handled by the
router.
This command shows how a call flows through the system. Using this debug level, you can see the call
setup and teardown operations performed on both the telephony and network call legs.
Sample Display
The following output shows the call setup indicated and accepted by the router:
router# debug voip ccapi inout
cc_api_call_setup_ind (vdbPtr=0x60BFB530, callInfo={called=, calling=, fdest=0},
callID=0x60BFAEB8)

The following output shows the caller entering DTMF digits until a dial-peer is matched:

The following output shows the call setup over the IP network to the remote router:
ccCallSetupRequest (peer=0x60C0E710, dest=, params=0x60A7B0A8 mode=0, *callID=0x60B6C110)
ccIFCallSetupRequest: (vdbPtr=0x60B6C5D4, dest=, callParams={called=14085241001,
