You can reduce your IP infrastructure costs even further by using high-performance gateways and standardized compression procedures. HiPath 8000 V3.1's “Any-to-Any” IP payload switching ensures that you get the highest availability and quality. Resiliency, Redundancy and Reliability HiPath 8000 software runs on highly reliable, fault-tolerant industry-standard servers under the Linux SLES 9 operating system. Clustering software protects against hardware and software failures, and controls failover of redundant Ethernet links and cluster nodes (redundancy is optional for systems below 5000 lines). By ensuring that all functions and applications maintain unrestricted availability, HiPath 8000 provides a new level of quality in IP communications. HiPath 8000 controls and supervises call setup; the actual voice traffic is carried over the LAN/WAN between endpoints. Administration/signaling and billing traffic is carried over a redundant pair of network interface cards through redundant, interconnected L2/L3 switches that provide redundant networking. The two servers may be collocated or geographically separated. If geographically separated, the connections between the two nodes may be established at the layer 2 level, using a tunneling protocol such as L2TP, or at the layer 3 level using IP routing protocols. HiPath 8000 utilizes Fujitsu Siemens Computers (FSC) PRIMECLUSTER clustering software and Resilient Telco Platform (RTP) middleware to provide a highly reliable platform which can operate in both active-active and active-standby mode, and can switchover automatically without loss of active calls or billing records. HiPath 8000 also provides a Survival Authority (SA), a separate component which normally resides on the HiPath 8000 Assistant administration server. The SA can assist in determining the proper cluster response in the event that communication between the two nodes is severed due to a network failure. Activation of the Survival Authority is optional in the case of collocated cluster nodes, but required in the case of geographic separation of the nodes.

For installations with fewer than 5000 users, the Assistant can be installed on the same server as the HiPath 8000 software and the integrated HiPath Media Server. In installations with more than 5000 users, it is necessary to install the HiPath 8000 Assistant, as well as the HiPath Media Server, on a separate, external server. RTP Command Line Interface HiPath 8000 system provisioning and administration can be performed using a traditional command line interface (CLI). Features/functions which must be activated or provisioned only once are still managed using the RTP CLI, e.g., tracing and other maintenance functions. The RTP CLI is always accessible via a secure shell, and can be accessed via Assistant or directly from the maintenance port of the HiPath 8000. Deployment Service The Deployment Service (DLS) is a management tool used for administering workpoints in the HiPath 8000 network. DLS is a Java-based application with a Web-based user interface, and is functionally integrated into the HiPath 8000 Assistant. The DLS is required to support the mobility feature on Siemens SIP endpoints. It provides options to migrate existing workpoints and to implement mobile user standards. Other important functions of the DLS include software deployment, inventory data management, configuration management, and Plug and Play support. HiPath 8000 V3.1 Media Servers The HiPath 8000 V3.1 offers the following media server options: ● ● RadiSys Convedia CMS-3000 media server for up to 360 ports HiPath Media Server for up to 100 ports (on the HiPath 8000) or 150 ports (on an external server) Multiple media servers can be employed for large installations or for added reliability. RadiSys Convedia CMS-3000 The RadiSys Convedia CMS-3000 is a turnkey, high performance media server for enterprise-sized HiPath 8000 network deployments. HiPath Media Server The HiPath Media Server is an integral part of HiPath 8000 systems for medium-size enterprises supporting 300-5000 subscribers. This software-only server solution provides tones, announcements and user prompts to support the functionality of HiPath 8000 features. Announcements are generated in the language requested by the HiPath 8000, or in a configurable default language. The HiPath Media Server also supports redundancy and station controlled conferencing. With HiPath 8000 V3.1, the HiPath Media Server supports media encryption using Secure RTP (SRTP) and the MIKEY key management protocol. The RG 8700 V1.2R1 software adds SIP-Q functionality for connectivity to HiPath 4000 and third party products which support QSIG. The HiPath Media Server can be installed on the same server as the HiPath 8000 system software for systems with under 5000 subscribers, requiring no additional hardware, or on an external server (the same server as HiPath 8000 Assistant), or on a separate, standalone server, or on any combination of these options. The RG 2700 gateway, designed for organizations with a head office and small- to mediumsize branch offices, is used for cross-site networking. This SMG includes a built-in SIP proxy that provides continued inbound and outbound calling service for up to 30 subscribers when the connection to the central HiPath 8000 system is temporarily lost. HiPath 8000 V3.1 Media Gateways To access the public switched telephone network (PSTN), the HiPath 8000 V3.1 solution provides the following gateway options: ● ● ● ● HiPath 4000 Survivable Media Gateway RG 8700 Survivable Media Gateway RG 2700 Survivable Media Gateway Mediatrix gateways Survivable Media Gateways (SMG) In branch offices with a HiPath 4000, survivability is made possible through the use of a Comdasys Convergence SIP proxy. This proxy takes the registrations from the phones and the HiPath 4000 gateway and passes them to the HiPath 8000 via the WAN. If the HiPath 8000 drops out or does not respond in a timely manner, the local SIP proxy takes over and tries to mediate the calls, including routing PSTN calls through the HiPath 4000 gateway. When connectivity to the HiPath 8000 is re-established, the proxy resumes forwarding the requests to the HiPath 8000 as usual. The RG 8700 provides a complete Siemens solution for HiPath 8000, as well as basic survivability for branch offices in the event of network failure. Survivability, a standard feature of the RG 8700 gateway, is accomplished through the use of SIP phones that are dual-registered with the HiPath 8000 and the RG 8700. If the RG 8700 can no longer communicate with the HiPath 8000, it switches to survivable mode, allowing the dual-registered SIP phones access to the PSTN trunks and, conversely, allowing incoming calls from the PSTN to be distributed directly to the SIP phones. The RG 8700 family of Survivable Media Gateways comprises 3 models that interwork with HiPath 8000 V3.1: RG 8716 with up to 16 T1/E1 spans, RG 8708 with up to 8 T1/E1 spans, and RG 8702 with up to 2 T1/ E1 spans. No license is required. Small Branch Office (SBO) Gateways These gateways connect endpoints in a small office scenario. Gateways from Mediatrix, with optional survivability provided by Comdasys, connect these locations to the HiPath 8000. Customers can also continue to use their previously installed third-party SIP gateways with the HiPath 8000. The supported functionality depends on how these gateways adhere to the relevant SIP standards. Interoperability testing may be required to confirm feature behavior. The HiPath Ready Lab is available to vendors seeking to certify their products with the HiPath 8000.

Unified Communications as a Service HiPath 8000 Server Technical Data Siemens' Unified Communications as a Service (UCaaS) is much richer than mere hosted telephony. UCaaS offers a modular approach to building applications, allowing enterprises to select the feature sets they need today, with the flexibility to change them or add to them in the future. The HiPath 8000 software runs on highly reliable, fault-tolerant industry-standard servers, providing carrier-grade reliability. The hardware configuration includes an IBM System x3650 T server, or two servers for fully redundant operation. For installations with up to 5000 users, redundancy is optional, so the second server is not required. The operating system is SUSE Linux Enterprise Server 9 (SLES 9); a SolidTech database is running on each server. The flexibility inherent in UCaaS allows customers to not only grow, but to do so at their own pace. UCaaS provides growth choices ranging from basic telephony to business process-embedded, presencebased rich communications environments; from contact centers with remote agents optimized through group- or skill-based call routing to multimedia-based and presenceenhanced contact center solutions. Whether your goal is interoperability with an existing communications infrastructure in order to optimize existing investments, or inexpensive migration to a survivable remote office, these choices and many other Data Center Deployment options are made possible through Siemens’ commitment to Open IT-based Communications.
