Auto answer and intercom / paging

[Aries21]

Hello -

We setup an asterisk server and wish to do paging on these phones. However, phone just rings. Google search suggests there are various alert-info headers that can be sent to make phone auto answer however none of them are successful. There are also various comments on these forums containing the same info but do not work and/or examples are incomplete.

Is it possible for these phones to auto answer an incoming call requested by server? If so, exactly how is this done -- what must appear in the sip headers and phone configurstion ?

Thanks!
