PowerConnect J-SRX210 Services Gateway Hardware Guide Basic Functions The availability of hardware and software for voice and data transmission on the same device is called integrated convergence services. J-SRX210 Services Gateway with Integrated Convergence Services implements a media gateway and a survivable call server. The J-SRX210 Services Gateway with Integrated Convergence Services integrates voice and data capabilities and provides a generic SIP-based voice over IP (VoIP) Media Gateway (SVMG) capability for local public switched telephone network (PSTN) and legacy analog/fax/phone connectivity. This feature enables standard phones to be used for voice calls over the Internet. The J-SRX210 Services Gateway with Integrated Convergence Services performs the following basic functions: • Bridges the VoIP network to the PSTN so that calls can be made from remote SIP and PSTN phones and routed to local analog telephones, fax machines, and local SIP phones behind the media gateway. • Assumes the call routing role as a survivable call server for local SIP or Analog phones, in the event of loss of WAN connections. • Supports emergency calling (E911) by providing the mechanism to detect emergency calls from local VoIP phones and passes these calls to the PSTN when detected. • Provides power failover support for one analog phone and PSTN FXO port. Supported Features The J-SRX210 Services Gateway with Integrated Convergence Services also offers the following additional features: • Digit manipulation for remapping digits • Caller ID support for detection and transmission of caller information (for U.S. standards) • Call waiting for SIP and analog phones in which the user is alerted about a pending, incoming call • Call hold and resume in which SIP calls may be placed on hold and resumed by the SIP phone user • Call waiting and call forwarding • Local auto attendant with a standard workflow, allowing the caller to enter an extension number to reach the call destination • Voice mail answering and retrieval through PSTN digit mapping 36
