Hardware SBC Compatibility
Your Questions, Answered
1. Why do interoperability issues occur when all devices support SIP?
Although SIP is an open standard, different vendors may implement it in slightly different ways. Variations in protocol interpretation, feature support, and codec compatibility can lead to connection issues, audio problems, or feature mismatches between devices. Session Border Controllers (SBCs) help bridge these gaps by normalizing SIP signaling and ensuring seamless interoperability.
2. How does an SBC solve interoperability issues?
Session Border Controllers (SBCs) address interoperability challenges by normalizing SIP signaling through message and header manipulation. They can modify, add, or remove SIP headers to ensure compatibility between different vendors’ implementations. Dinstar SBCs offer regular expression-based and programmable SIP adjustments, allowing seamless communication across diverse VoIP systems.
3. How does an SBC prevent traffic overload?
An SBC intelligently manages traffic based on user level and business priority, ensuring critical services remain uninterrupted. With high overload resistance—handling up to 3 times the normal load—it prevents service disruptions. Features like traffic control, dynamic blacklisting, and call rate limiting help maintain network stability and security.
4. What causes traffic overload?
Traffic overload is often triggered by high-demand events, such as significant sales, large public events, or sudden surges due to negative news coverage. Additionally, unexpected spikes in registrations caused by data center or network failures can lead to overload situations.
5. Why is a Session Border Controller (SBC) needed to prevent VoIP attacks?
Some VoIP attacks follow standard protocols but exhibit abnormal behavior, such as excessively high call frequencies that can harm your VoIP infrastructure. SBCs provide deep application-layer analysis to detect and mitigate suspicious activities, ensuring network security and stability.
6. How does an SBC help with NAT traversal in VoIP?
Network Address Translation (NAT) modifies private IP addresses to external ones but does not update the application layer IP, causing VoIP communication issues. An SBC detects NAT, adjusts the IP address in the Session Description Protocol (SDP), and ensures RTP traffic reaches the correct endpoints, enabling seamless connectivity.
7. What is a Session Border Controller (SBC) and why is it important?
A Session Border Controller (SBC) is a network element designed to protect SIP-based VoIP networks by ensuring secure and reliable communication. It has become the industry standard for telephony and multimedia services in Next-Generation Networks (NGN) and IP Multimedia Subsystems (IMS), providing security, interoperability, and traffic management.
8. How does an SBC improve call quality and manage multimedia traffic?
Managing multiple systems and multimedia traffic can be complex, often leading to network congestion and poor call quality. SBCs analyze audio and video calls based on user behavior and implement intelligent call routing using caller details, SIP parameters, time, and QoS metrics. When network instability causes packet loss or jitter, SBCs monitor call quality in real-time and take immediate corrective actions to maintain a high Quality of Service (QoS).
