For Avaya phones that support the ability to auto-answer calls when requested to do so by the system, that feature is enabled automatically and does not require any configuration.
However, for 3rd-party SIP phones there are multiple methods of signalling that a call should be auto-answered. If the phone supports one of those methods, that needs to be configured through 3rd Party Auto Answer field in the extension settings. Supported options are:
3rd Party Auto Answer Setting Value
Description
None
The extension device does not support auto answer.
RFC 5373
The extension device supports auto answer using an RFC 5373 header added to the call invitation message.
answer-after
The extension device supports auto answer using a 'answer-after' header message.
device auto answers
The system relies on the extension device auto answering calls. The IP Office does not indicate to the device that it should auto-answer a call.
