Sonus products work together to provide intelligent, secure, reliable and scalable Internet Protocol (IP)-based interconnect. The core data and voice networks within most global telecommunications service providers are now predominantly IP-based. Wherever possible, service providers are adopting IP due to cost advantages, the extended service reach it provides and its proven resiliency. While IP-based communications offer many significant benefits at the interconnection point between peering partners, the use of IP comes with its own set of challenges.

At the core of the challenge is the fact that IP peering connects disparate IP networks. Service providers must overcome interoperability, security and routing challenges when connecting independent networks and still be able to reliably scale their services. Sonus’ peering solution provides industry leading security such as network topology hiding, Distributed Denial of Service (DDoS) protection, and per session encryption as well as providing reliable connectivity between Time-Division Multiplexing (TDM), Session Initiation Protocol (SIP)-based and IP Multimedia Subsystem (IMS)/Long-Term Evolution (LTE) networks. Intelligent routing policies allow Least Cost Routing (LCR), routing based on connection quality as well as routing based on over 200 parameters such as origination number/gateway, partition, holidays and codec type.

Any peering solution must be able to enable tracking and billing for any minutes traversing the network. The Sonus solution provides reliable, scalable Call Detailed Record (CDR) generation and can easily integrate into multiple billing systems.

Expect More from the Sonus Interconnect Solution:

1. Complete network protection from theft of service and attack, including Denial of Service (DoS) and Distributed Denial of Service (DDoS)
2. Feature-rich interworking across voice, video and collaboration without compromising performance or scale
3. Intelligent Routing – built-in LCR, Local Number Portability (LNP) and multimedia routing
4. Can be deployed on purpose-built appliances or in private/public Clouds as a virtual solution

Benefits:

The Sonus Interconnect solution is designed to sit at the border between carriers and provide an intelligent interconnection between partner networks. Critical to any peering environment, the solution delivers the following functions:

• Secures the network border
• Enforces Quality of Service (QoS) policies with intelligent routing – provides easy migration to an LCR and quality-based routing solution
• Transcoding media and providing codec interworking, Dual-tone Multi-frequency (DTMF) and fax interworking
• Traversing intermediate Network Address Translation (NAT) and firewalls
• Ensuring Call Detail Record (CDR) generation and storage
• Flexible deployment models in either a hardware-based appliance or virtualized environment

Advantages of the Sonus Solution:

• Interworking across Web, IP and legacy protocols–– WebRTC, IP (H.323, SIP, SIP-I, SIP-T), and TDM
• Easily integrates into existing business support systems (BSS)/operations support systems (OSS) to enable migration from existing TDM assets to IP
• Delivers scalable security – encryption and DoS protection that can scale as your interconnection points grow
• Integrated LCR, LNP options to lower costs and increase voice and video quality

IPX is a technical and business model standard defined by the GSM Association (GSMA) that mobile service providers use to transmit Long-Term Evolution (LTE) Data, Voice over LTE (VoLTE), LTE signaling, roaming and other services outside of their own networks.

Wholesale service providers and GPRX Roaming Exchange (GRX) operators are looking for new multimedia interconnect services to improve monetization. When making the move to implement new services they must overcome complex interoperability, security and service quality challenges when interconnecting disparate fixed and mobile Internet Protocol (IP) networks.

For IPX network providers, Sonus delivers a solution with the security, policy control, and signaling and media interworking needed to ensure IPX network providers success in the following:

• Revenue growth in new markets by offering new IP exchange services
• Reliable security for every network peering point
• Support for service types including Video, HD Voice over IP (VoIP), Multimedia and Rich Communications Suite (RCS)
• Flexibility in deployment either on dedicated hardware or in a virtual environment for additional CAPEX and OPEX savings

The Sonus IPX solution is comprised of:

Session Border Controllers (SBC)

• Security (IP Topology hiding, DDOS prevention, TLS/IPSec)
• Signaling interworking and media transcoding
• 10G interface connectivity
• IP Multimedia Subsystem (IMS) edge and interconnect functions – P/E/I-CSCF, I-BCF

Policy Management and Routing (PSX)

• Centralized routing
• Number portability
• Session routing proxy – IMS Border Gateway Control Function (BGCF)

Diameter Signaling Controller (DSC)

• Diameter Routing Agent (DRA) and load balancing
• Diameter Edge Agent (Topology Hiding, TLS/IPSec)
• Subscription Location Function (SLF)
• Message counting for accounting / billing
• Interworking with other IPX, 4G/LTE as well as 2G/3G networks

Seamless mobile voice and messaging over Wi-Fi

Voice over Wi-Fi (VoWiFi) is the industry standard approach for mobile service providers seeking to deliver voice and SMS/MMS services over Wi-Fi. With VoWiFi, mobile subscribers receive a seamless voice and messaging experience as they move between the macro-cellular network and existing Wi-Fi networks, such as those at the office and home.

With VoWiFi, subscribers can now receive high-performance mobile services in the exact locations they spend most of their time. It also provides a low cost international roaming solution as users can make and receive mobile calls as if they were on their home network when connected to any Wi-Fi network around the world.

For MNOs, VoWiFi addresses indoor coverage challenges in the precise locations that are typically difficult to reach with the macro network. As a result, they can see lower churn due to improved service coverage, as well as lower costs due to increased network offload.

For MVNOs and other alternative mobile service providers, VoWiFi enables adoption of a Wi-Fi First strategy. With Wi-Fi First, all subscriber voice and messaging traffic, when connected to Wi-Fi, stays on net rather than using minutes and messages from their macro cellular network partner.
