I am trying to set up paging between 2 cisco 8961 phones. I have added 2 ext for each phone. one for main outbound calls and 1 for paging. The one for paging, I have set internal Auto answer = Intercom.
The phones ring when you try but the auto answer never picks up it just rings and rings. I output for asterisk is

</line>

in the sip stack I have

<autoAnswerTimer>0</autoAnswerTimer>
<autoAnswerAltBehavior>true</autoAnswerAltBehavior>
<autoAnswerOverride>false</autoAnswerOverride>

What am I missing???

Within the <sipLines> section of your phone config file, you will need to change from <autoAnswerEnabled>0</autoAnswerEnabled>

to be

<autoAnswerEnabled>3</autoAnswerEnabled>
