Ribbon Communications: Reliable VoIP Solutions

Implementing VoIP (Voice over IP) in corporate networks is gradually becoming the norm not only in Europe and the United States but also across many CIS countries. Companies in Ukraine, Georgia, Kazakhstan, and Azerbaijan actively switch to IP telephony to optimize communication expenses and enhance the flexibility of corporate interactions. However, along with the advantages of VoIP, security and compatibility risks are also on the rise. Cybercriminals view voice traffic as a new entry point for attacks, while engineers need to adapt systems to local requirements and specific hardware constraints.

In this article, we will examine how Ribbon Communications contributes to VoIP adoption and how their solutions—Session Border Controller, EdgeMarc, EdgeView, and other products—help organizations establish a secure, reliable, and scalable IP telephony environment. We will also discuss why NWU, as an official distributor of Ribbon solutions in Ukraine, Georgia, Kazakhstan, and Azerbaijan, provides a comprehensive approach to integration and support for such projects.

VoIP Security with Ribbon: How and Why

The Threat of Cyberattacks and Data Protection

Cybercriminals are increasingly targeting voice systems, especially those that rely on poorly secured SIP trunks or outdated equipment. Unauthorized access to a corporate network can lead to the theft of confidential information, unauthorized paid calls at the company’s expense, or even eavesdropping on internal negotiations. In Ukraine, Georgia, Kazakhstan, and Azerbaijan, such attacks often focus on the financial sector, IT companies, and telecom operators.

To counter these threats, organizations must implement a comprehensive security strategy, which includes encrypting SIP traffic, protecting against DDoS attacks, and complying with international standards such as PCI DSS and GDPR. Ribbon Communications provides the necessary tools through Session Border Controller (SBC) solutions, strengthening corporate segments by means of advanced authentication and session-control mechanisms. Additionally, SBCs act as a “central gateway,” blocking malicious requests and ensuring end-to-end encryption.

Key Challenges in VoIP Deployment

1. Complex Integration. Real-world networks consist of diverse hardware—ranging from legacy analog PBXs and routers to modern IP-PBXs and cloud-based UCaaS platforms. A seamless transition is required to avoid disruptions and prolonged downtime.
2. Flexibility and Scalability. Rapidly growing businesses in Azerbaijan or Kazakhstan do not want to overhaul their infrastructure each time they open a new branch. They need solutions that can “handle” a growing user base, extended bandwidth, and the addition of new services.
3. Compatibility and QoS. Issues with codecs, different SIP versions, or unstable network capacity can degrade call quality.

Why Companies Need a Session Border Controller

A Session Border Controller (SBC) serves as a kind of “fortress” at the edge of the network. It protects your voice and multimedia traffic from external threats and monitors traffic within the organization. Ribbon’s SBC solutions go beyond basic filtering and additionally support:

• Encryption of media streams (SRTP) and signaling traffic (SIP-TLS).
• Intelligent call management, including traffic rerouting and policy control.
• DDoS and SIP attack blocking based on signature analysis.
• Integration logic with other network services (IDS/IPS, firewalls, analytics systems).

Ribbon SBC: Key Advantages

1. High Throughput: Top-tier models can handle thousands of concurrent calls with minimal latency.
2. Flexible Deployment: Available as hardware appliances and as virtual SBCs (vSBC) for quick deployment in public clouds (AWS, Azure) or private data centers.
3. Built-in Encryption Mechanisms: Support for modern security protocols aligns with international regulations.
4. Advanced Monitoring Tools: Real-time metric collection and traffic analysis simplify troubleshooting and fault resolution.

EdgeMarc and EdgeView: Who They Are and Why They Matter

In addition to a “classic” Session Border Controller, Ribbon offers EdgeMarc and EdgeView. These solutions manage traffic at the “network edge” and enable centralized administration of distributed locations. This capability

is crucial for companies with multiple offices in different countries—for example, when the main office is in Ukraine and the branches are in Azerbaijan and Georgia.

• EdgeMarc: This device provides remote monitoring and management of WAN connections. It observes key VoIP metrics such as MOS (Mean Opinion Score), jitter, latency, and packet loss. EdgeMarc automatically switches traffic to a backup line if the primary link fails.
• EdgeView: A platform for centralized administration that tracks hundreds of EdgeMarc devices across different locations. It issues alerts about outages, evaluates call quality, and generates reports for further optimization.

Together, EdgeMarc and EdgeView streamline VoIP network scalability: you can quickly spin up a new branch in Kazakhstan or another international site with predefined policies and routing.

Practical Implementation Scenarios

1. Small and Medium-Sized Businesses: Suppose a company with offices in Ukraine and Georgia wants to cut down on costly international calls by switching to a unified VoIP service. Ribbon’s SBC 1000 can serve as the core gateway, ensuring strong encryption and basic analytics. Meanwhile, an EdgeMarc at each location manages local traffic flow and provides backup internet connectivity.
2. Large Corporations: A multi-layered organization with several branches in different cities of Kazakhstan, Azerbaijan, or other countries can simplify call routing by deploying an SBC 5000 or higher. This approach is ideal for hundreds or thousands of concurrent sessions. At the same time, EdgeView coordinates all EdgeMarc devices in every branch, eliminating manual configuration and minimizing human error.
3. Cloud Environments: Some companies opt for a complete shift to the cloud. Ribbon offers virtual SBCs (vSBC) running on AWS, Microsoft Azure, or Google Cloud, delivering a flexible, high-performance solution without the extra cost of physical hardware.

Critical Security Considerations

1. Encryption: Using SIP-TLS and SRTP is essential these days. It’s also crucial to configure certificates correctly to prevent man-in-the-middle attacks.
2. ACL Policies: SBCs and routers should have clear access control lists (ACL). Blocking all unauthorized connections is vital to thwart SIP account breaches.
3. Monitoring and Auditing: Regularly review logs and reports from SBC, EdgeMarc, and EdgeView. Quickly spotting anomalies—like traffic spikes or unauthorized nighttime calls—can avert significant losses.
4. Update Strategy: Any defense system must be regularly updated to address new vulnerabilities. Ribbon releases periodic patches that should be installed promptly.
