Cisco IOS Software Features on Cisco 880 SRST Series: Advanced IP Services Feature Set Feature Description Cisco SRST version SRST 7.0 and later are supported. Call-control signaling H.323 Versions 1, 2, 3, and 4, Media Gateway Control Protocol (MGCP) 0.1 and 1.0, Skinny Client Control Protocol (SCCP), and SIP call-control protocols are supported. ITU standard voice codecs G.711, G.729, G.729a/b, G.723.1, G.726, and G.728, which are standards-based compression technologies allowing transmission of voice across IP, are supported. The G.711 standard employs 64kbps pulse code modulation (PCM) using either mu-law or a-law. Other codecs employ lower bit rates. Cisco Unified Communications Manager support For SRST features for IP phones, refer to the SRST data sheet at: http://www.cisco.com/en/US/products/sw/voicesw/ps2169/products_data_sheets_list.html. Cisco Unified Communications Manager support for analog and digital ports come with Releases 6.1(3), 7.0(2), and 7.1(3). Telephony interface signaling support Cisco 880 SRST supports the following signaling protocols: ● FXS loop-start and ground-start signaling ● FXO ● Inbound signaling (such as dual-tone multifrequency [DTMF] and multifrequency support) ● BRI QSIG Voice features ● Echo cancellation: This feature cancels echo on tail circuits up to 64 msec (configurable tail length). ● Silence suppression and voice activity detection (VAD): Bandwidth is used only when someone is speaking. During silent periods of a phone call, bandwidth is available for data traffic. ● Comfort-noise generation: This feature reassures the phone user that the connection is being maintained, even when no voice packets are being transmitted. ● Caller ID support: Per-port caller ID (with per-call unblocking) is configurable over analog FXS. ● Dial-plan mapping: This feature simplifies configuration and management through automatic mapping of dialed phone numbers to IP addresses. Voice port-specific features ● FXS: FXS provides battery polarity reversal detection and initiation for disconnect supervision and farend answer supervision. ● ISDN BRI network side and phantom power: The BRI port provides the ability to connect a private branch exchange (PBX) or private automatic branch exchange (PABX) configured as user side directly to the router. It also provides phantom power to accommodate equipment that requires it. ● LED indicators show voice-processing resources and port status. Fax and modem ● Fax and modem pass-through allows fax and modem traffic to pass through a voice port. ● Fax Relay provides a more robust protocol for fax transmission over packet networks. It also supports the T.37 and T.38 fax protocols. High-performance flexible digital-signalprocessor (DSP) architecture ● Channel capacity: Cisco 880 SRST supports up to four voice channels. ● Flexible DSP architecture: There is no need to specify codec complexity at configuration. An appropriate codec is dynamically selected when a call is established, while allocating DSP resources optimally. ● Feature upgrades: The DSP architecture allows for addition of new features through simple code updates. © 2010 Cisco and/or its affiliates.
