Description
The cc_RetrieveAck( ) function allows the application to accept a request to
retrieve a call from hold from remote equipment. The call must be in the Hold
state and the CCEV_RETRIEVECALL event must be received before the
function is called.
Parameter Description
crn: The call reference number. Each call needs a CRN.

Cautions
• The BRI protocols and the PRI Q.SIG protocol are the only protocols that
allow the retrieval of a call in the Hold state to be accepted or rejected. The
cc_RetrieveAck( ) function cannot be used in the DPNSS protocol or any
PRI protocol other than Q.SIG.
• The cc_RetrieveAck( ) function is valid only after the call is in the Hold state
and after the CCEV_RETRIEVECALL event is received.
