A result code.

DESCRIPTION

You can use the TELAnswerCall function to answer a call that is alerting at the telephone terminal. When a call is alerting, your call appearance message handler receives a telCAAlertingMsg message.

You can also use TELAnswerCall to answer a call that is being offered at a telephone terminal. (Your call appearance message handler receives a telCAOfferMsg message when a call is being offered.)

If TELAnswerCall returns noErr, the state of the call appearance changes to telCAActiveState and your call appearance message handler receives a telCAActiveMsg message. At this point, an end-to-end connection exists and communication can take place.

SEE ALSO

Calling the TELAcceptCall function (page 4-29) is also a valid response to a CAOfferMsg message. See the description of the CAOfferMsg message for more information about alternative responses to the message.
