On-premise appliance for IP telephone provisioning, call processing, and device management. Enables Level365 to deliver secure VoIP connections, monitor voice quality, and quickly remediate issues. Provides failover to an alternate internet connection when the primary internet connection is lost, keeping your essential voice services online.
Session Border Controller (SBC)
Level365 positions the SBC at the network perimeter (or border), so it can control and secure the voice traffic and connected devices. The controller connects directly to the internet service provider and runs parallel to any network firewall or router. At this level the SBC performs three primary functions- delivering consistent connectivity, keeping calls and devices secure, and reducing downtime by allowing for a failover to a secondary internet connection.
Whether due to lost productivity or lost revenue, downtime of business-critical systems can be costly. In addition to our cloud-based services, Level365 can increase call availability by leveraging two internet connections for the controller to utilize. This allows the telephones to automatically failover to a secondary internet service which keeps users online and reduces downtime due to a circuit outage.
Internet firewalls are designed to protect the local network by keeping unwanted traffic out. For voice services, this can lead to communication problems such as one-way or no audio on calls, inconsistent ringing, and telephones not being able to register online. By deploying the SBC, which is a firewall specifically designed for SIP applications, Level365 avoids these pitfalls. This allows for the best user experience, greatly reduces issues, and leaves the voice services in the hands of the experts.
VoIP services and IP telephones are frequent targets of attacks. Some common VoIP attacks include:
- Service theft & fraud: Attackers accessing a VoIP system to route traffic and use network resources without paying for them
- Spoofing: Deliberately modifying or disguising an identity (for example, caller ID) on the network
- DoS/Distributed Denial-of-Service (DDoS) attacks: Flooding a server or SBC with requests to overwhelm its available resources
Level365 thwarts these by utilizing the SBC to protect services and employees via encryption, topology hiding, traffic policing, and call admission control. The SBC only communicates with Level365 cloud servers, preventing unauthorized access and attacks. We also ensure that conversations are secure by encrypting the signaling to prevent communications from being illegally intercepted or tampered with as well as maintaining privacy.
