Audio/Fax Stream Mode

Determines the streaming mode for audio, fax, and media transmission.

  • DSP: the audio/fax stream is processed using a DSP resource, and consumes a DSP license.
  • Proxy: the audio/fax stream is processed using the SBC internal processing resources and does not require a DSP resource or license.
  • Direct: the audio/fax stream is passed directly from one compatible end-point to another, this uses neither the SBC processor or a DSP resource.

All three options are enabled by default.

Specifies how ringback is played on a channel.

Note
iconfalse

The Play Ringback configuration functions with only 180 Ringing or ISDN Alert. The function is not executed for 183 w/SDP.

  • Auto: Configured for Auto, the Sonus SBC 1000/2000 operates in the nominal RFC 3960pattern
    • Sonus SBC 1000/2000 generates ringback until in-band media arrives.
    • Sonus SBC 1000/2000-generated ringback is discontinued in the presence of in-band ringback.
    • Additionally, any ALERT is sent with PI=8 regardless of whether or not a SDP was received on the SIP side. Doing so allows the Sonus SBC 1000/2000 to send in-band audio without signaling PROGRESS.

  • Always:Sonus SBC 1000/2000 provides ringback, ignoring any arriving in-band media.
    • For SIP-originated call legs, 180w/SDP will be sent to permit Sonus SBC 1000/2000 to provide in-band ringback via early media.
    • For ISDN-originated call legs, ALERT+PI will be sent along with Sonus SBC 1000/2000-inband ringing.

  • Never:Sonus SBC 1000/2000 does not provide ringback and cuts through ringback from the source when/if it arrives.
    • With NEVER, Sonus SBC 1000/2000 will send 180/ALERT to the originating call leg without SDP/PI as in this configuration Sonus SBC 1000/2000 will not supply inband ringback.

(info) Note: The Play Ring Back setting is activated only after the channel receives an ALERT or 180 Ringing. Issues with ringback and 183 Session Progress must be addressed using a Message Translation.

The Ringback setting will be activated if a Message Translation's output is ALERT/180.

The Ringback setting is not used for ISDN-to-ISDN calls when the ALERT contains a Progress Indicator. Sonus SBC 1000/2000 will always set the outgoing PI as it was received.
