[Asterisk-Users] Special Delivery from China

[James H. Thompson]

The one thing not available in any low cost SIP phone is auto-answer controllable via SIP.
i.e. enable microphone only, enable speaker only, or enable both.
Grandstream has an option to enable auto answer in its configuration screen, but since once enabled,
it always auto-answers and it only has one line appearance, its not much use.

You need this feature to do paging and intercom with handsfree talkback.
See:

for more information.
