    Specifies when to generate local ring back Auto: Depends if inband audio is available Always: Always generate inband ringback Never: Never generate inband ringback.

    Both can indicate early media with SDP. If there is no SDP, the end device (softphone/gateway/etc.) has to generate the ringback tone or progress tone. Usually.Posted 7 July 3 min.

    A normal SIP call successfully established when the callee accepts it this response usually initiate a local ringback to the end user.While there is no formal prerequisite needed to read this document; it was written with the expectation that the reader already has some working knowledge of underlying voice signaling protocols that are used to establish and connect phone calls.

    Our Asterisk PBX is connected to a VoIP provider via SIP trunk. When making calls that go thru this trunk, we hear a double ringback tone.However there do exists commands to change the behavior in the event of an interopability requirement.

    Ringback and other call progress tones are not generated by the Cisco Annunciator, as is the case for regular phones and softphones.

    When testing against a different VoIP provider that actually does send the ringback tone via the SIP trunk, the double ringback problem does not happen - in this case the phone somehow knows that there is an incoming RTP ringback and does not generate it's own.
