Enterprise Session Border Controller (E-SBC) used by Enterprise have special needs

The Enterprise SBC or E-SBC you choose is critical to real-time video and voice services. These services are mission-critical for business and service assurance. Voice must meet the 99.999% availability threshold. Dropping any call is unacceptable and the audio listening experience must be impeccable or you can loss valuable information that will reduce selling opportunities and/or cause support frustration. While increasingly video is becoming critical to daily needs in customer support, sales and operations.

Teraquant understands that Enterprise networks exist to serve evolving and unique business needs. This is why our approach to solution starts by removing vendor dependencies from your network. This frees you to use best in class components and to make incremental changes. With this in mind we work with you to simplify the network to optimize performance while we better align it with your evolving business needs. We focus on reducing risk while enabling proactive issue prevention and if you have a problem we ensure you have the industries best issue isolation and fastest resolution.

What’s New for Enterprise SBC (E-SBC)

Here are a few examples of the new ways we can help with E-SBC selection and deployment for your changing Unified Communication (voice, video and data) network needs. We can help address business driven real-time network needs regardless if the needs are: On premise, UCaaS, multi-cloud, hybrid UCaaS, or adding remote users.

Virtual SBCs using Session Border Controller Network Function Virtualization (VNF) is gaining momentum in traditional and cloud-based UC Networks. It enables them to rapidly introduce innovative services and also to more efficiently utilize cloud infrastructure resources.

  • Network functions virtualization (NFV) is a network architecture concept that uses the technologies of IT virtualization to virtualize entire classes of network node functions into building blocks that may connect, or chain together, to create communication services.
  • Oracle Communications Session Border Controller VNF deployments require configuration of the virtual machine environment and of the SBC itself. The user can consider SBC configuration as separate from VNF configuration.
  • The Oracle Communications Session Border Controller VNF version is suited for deployment by a virtual machine manager. Oracle provides virtual machine templates specific to the hypervisor over which the product is deployed. Oracle hypervisors implement Non-Uniform Memory Access (NUMA) topology rules to automatically enforce such placements.
  • Oracle VNF hardware platforms have built in optimizations related to VM placement. Users should ensure that VMs requiring high media throughput are optimally placed by the hypervisor, so that traversal of cross-domain bridges, such as QuickPath Interconnect (QPI), is avoided or minimized.

E-SBC Product Offerings

ACME Packet E-SBC from Oracle

Frafos E-SBC

ORACLE ACME Packet E-SBC Key Features

Only Oracle E-SBC offers net-safe architecure to hide netowrk topology from hackers and add advance algorithms to provide security against real-time Denial of Service (DoS) attacks.

Defense against Denial of Service (DoS) attacks

Securely Connect Networks & Users of Varying Trust Levels

DoS protection is one of the unique features found in the Oracle Acme Packet SBC.

Securely Connect Networks and Users with Varying Levels of Trust

The Oracle Acme Packet SBC is the only SBC with sophisticated machine learning algorithms working at line rate to dynamically classify packets and block DoS – while it enables trusted communications to flow. The SBC will detect a suspect Telephony DOS attack in real-time and automatically throttle it down. The attacker’s thread is placed in a queue with the lowest priority for CPU utilization. CPU and other SBC resources are prioritized for trusted flows. If the profile of the attack increases the evidence that it is intended mischief, all packets from that source will be dropped.

During a Denial of Service (DoS) attack the Oracle SBC implements Deep Packet Inspection (DPI) to further assess the suspect nature of the traffic. Eventually, that traffic source will be placed in the Bit Bucket where the source of the SIP request gets no response of any kind. You can verify this by using traces too see that zero response is given back to the perpetrator.

Fuzzing Attacks

Here the hacker tries to send malformed IP or SIP packets towards your network with the hope that your SIP protocol stack breaks down and goes into some race condition or overload condition unable to interpret the SIP packet sent to it. The Oracle SBC knows SIP rather well after 20 years in existence. Any legitimate SIP implementation not recognizable or not part of any interoperability test program or certification is recognized as a fuzzing attack. The Back-To-Back User Agent (B2BUA) nature of the Oracle SBC prevents fuzzing attacks penetrating into your network. Incorrect and recognized implementations are ignored, and only legitimate SIP transactions and dialogues are regenerated into your internal private network.

A Back-To-Back User Agent (B2BUA) also does topology hiding which prevents any details of your internal network being visible to the outside and therefore stops reconnaissance scans of your internal IP telephony assets.

Message Flow

The Oracle Acme Packet SBC enables secure reachability from users outside your network, on a public network such as remote workers. It:

        • Monitors end-point behavior and dynamically assigns trust levels
        • Applies access controls to all communications traversing network borders
        • Prevents malicious reconnaissance


Protection of privacy has 2 parts:

Acme Packet E-SBC protects privacy with encryption. Encryption ensures communications flow cannot be intercepted. Strong encryption also prevents media injection and man in the middle interception. The Oracle Acme Packet E-SBC offers a wide range of cipher suites with varying levels of complexity versus resource overhead to provide you with the correct level of privacy for your communications. The SBC controls and polices your privacy policies for all traffic on your enterprise network. The government uses Oracle SBC for the most sensitive of applications. Accordingly, Oracle SBC’s are certified for US government FIPS and JITC compliant Tamper-proof administrative security.

Strong Authentication means the identity of the parties in the conversation have been identified by an independent authoritative third-party. This is not only assists protection against man in the middle attacks but also achieves non-repudiation.

Non-repudiation refers to a situation where a statement’s author cannot successfully dispute its authorship or the validity of an associated identity or contract.

Teraquant integrations can go beyond the E-SBC to add in Zero Trust Security to prevention theft of personal and confidential information including any Personally Identifiable Information (PII). Teraquant offers Secure Vector Routing (SVR) technology in our Session Smart™ Routers to add a much-needed layer of security. This security is separate from the security provided by services, applications, and server-farms within your enterprise.

Security Protection

IP Communications allows hackers to launch a vast array of Security Threats at an extremely high rate. Install an IP address on a public network interface and within minutes, bad actors will attempt to break in with SIP or fuzzing attacks. If the hacker detects any clue that a SIP entity/application sits behind that IP address he will persist with continuous attacks, draining your resources at the very least and often causing total Chaos.

Security vulnerabilities allow attackers to inflict 3 categories of damage on you and your clients:

        • Denial of Service – clogging resources, preventing legitimate users from accessing them
        • Privacy breach – theft of confidential information or interception and recording of private conversations
        • Telephony VoIP Fraud – misuse of your telephony assets & infrastructure to divert income to the fraudster by incurring stolen costs on you, the enterprise
Security Professional


STIR (Secure Telephony Identity Revisited) and SHAKEN (Secure Handling of Asserted information using toKENs) are the frameworks that promise to prevent the completion of illegally spoofed calls.

Such attacks are pervasive, frequent, persistent and most often these days, go undetected if sophisticated countermeasures are not implemented to detect them. Such attacks often result in lost revenue and productivity to you and a poor experience for your customers. They also create compliance violations and damage to your brand image.

Teraquant offers advanced integrated solutions to SIP/VoIP Fraud Prevention and we can implement robocall prevention with STIR/SHAKEN that works with your SBC.

Teraquant is proud to offer you two different vendors of Session Border Controllers to meet your specific needs.


For large-scale telcos/communication service providers and Enterprises, we supply the Oracle Communications (formerly Acme Packet) SBCs, which are the industry leader and most highly regarded devices for carrier-class communications.


For budget-sensitive applications, where a full set of features and carrier-class performance is required, the Frafos is unmatched. Frafos is produced by engineers that contributed to the very origins of VoIP/SIP. Headquartered in Berlin, Germany, Frafos is privately held by a founding team of young and seasoned entrepreneurs with Fraunhofer Institute pedigree.

The Fraunhofer Institute has researched and produced many leading communications technologies, for example including the MP3 codec.

Frafos innovates, virtualizes and secures telephone infrastructure with next-generation Session Border Controllers, WebRTC gateways and service assurance solutions, with a market focus on Tier 2 and 3 operators, Enterprises and the public sector.

First SBC deployment in 2012, and first WebRTC in 2013.


Choose the vendor that can grow beyond your needs. The Oracle SBC software is common across all hardware platforms. The high-end 6350 scales to 160,000 concurrent call sessions. These are Media sessions – one chassis and 16,000 sessions per VNF. The Oracle SBC is used in 90% of the largest 100 Telco’s. It meets scaling requirements for the largest voice networks in the worldwide.

IETF SIPREC protocol reduces cost and complexity

The Oracle SBC solution conforms with the RFC SIPREC specification which improves customer choice and flexibility by enabling interoperability across recording systems sourced from different vendors.

Oracles adherence to the IETF SIPREC implementation brings flexibility to support a range of network resiliency features. It can be deployed on a pair of SBCs in high availability configuration, leveraging Oracle’s unique active-active HA to ensure recordings are not affected by a fail-over condition. In addition, redundant SIPREC sessions can be established between a recording client and multiple recording servers to ensure recordings are not affected by a server failure. The protocol can also load balance sessions across multiple recording servers and the E-SBC and ISR can be configured to not accept an incoming call, if a recording resource isn’t available to record it.

        • Efficiently copies communications sessions centrally
        • Eliminates costly ACD licenses, mirrored ports and other infrastructure
        • Copies any call segment and copies sessions to multiple servers
        • Highly flexible, scalable and reliable
        • Provides access to session at ingress
        • recording can be enriched with metadata
        • Enables monitoring of entire customer experience (IVR, etc.)

Teraquant Solution Services will address your needs but they won’t bust your budget

As an example we can connect your on premise PSTN into MS Teams and MS 365. We can also help define E-SBC solutions for hybrid cloud or on premise SIP only networks.

Fraud Prevention

The most frequent Form of telephony fraud is International Revenue Share Fraud (IRSF). This type of telephony fraud typically involves illegitimate automated generation of outbound calls from your infrastructure to expensive destinations. Such destinations include:

        • International Premium Rate Numbers (IPRN)
        • Premium rate numbers in the Caribbean
        • Traffic pumping to domestic destinations offering for example, free conferencing services

All these fraud scenarios start with assessing vulnerability to gain access to your PBX infrastructure and generate outbound calls. If you have users located outside your enterprise telephony infrastructure, SIP registrations are permitted from these outside locations into your PBX based on user credentials or loopholes in your voicemail servers or via the management port of your PBX.

Your Oracle Acme Packet SBC can be used to block such outbound calls based on detection algorithms or black lists which block known fraudulent destinations. Teraquant offers integrated solutions to work with you SBC to enable the most sophisticated fraud prevention including a worldwide blacklist comprised of over 2 million IPRN numbers giving you immediate fraud prevention at your SBC. It also comes with ongoing updates to continuously update your fraud prevention. We also offer a STIR/SHAKEN or robo-call prevention add-on.
