Introduction

The Intercom feature allows the user's phone to ring for inbound calls that are not supposed to be intercom calls. If you do not require the use of the phone other than as an intercom, use the Auto-answer feature. Selecting Auto-Answer does not require modifying the Call-Info SIP Header.
