A 3CX SBC (Session Border Controller) is a component used in 3CX VoIP phone systems to simplify remote phone and office setups while keeping your network secure. What a 3CX SBC Does 1. Connects Remote Phones / Sites 2. Enhances Security 3. Simplifies Network Configuration 4. Supports Multi-Site Deployments How It Works 1. PBX is installed at the main office. 2. Remote phone (or branch office) connects to the SBC at the remote location. 3. SBC securely tunnels the call traffic back to the PBX. Key Benefits - Secure remote working - No VPN required - Better call quality for remote offices - Easy to deploy and manage

3CX Self Hosted 3CX Self-Hosted means you install and manage the 3CX phone system yourself, either: - On a cloud server (like AWS, Azure, Google Cloud, DigitalOcean, or any VPS provider), or - On your own hardware (on-premise, like a Windows/Linux server or a mini-PC). You are responsible for the server setup, configuration, security, updates, and maintenance. Key Features - Full control – you decide where and how the PBX runs. - Flexibility – deploy on-premise or on any cloud provider of your choice. - Customizable – integrate with CRMs, control network/firewall settings, and fine-tune performance. - Bring your own SIP trunks – connect with almost any provider. - Advanced configuration options – like SBCs (Session Border Controllers) for remote phones. Benefits - Greater control: You’re not limited to 3CX’s hosted environment. - Potentially lower cost: If you already have a server or cheap VPS, hosting yourself can save money. - More customization: Tailor the system to your exact needs (security rules, integrations, failover setups). - On-premise reliability: If you want phones to work even if your internet goes down, an on-site server can keep internal calls running. Challenges - More responsibility – you must handle updates, patches, backups, and monitoring. - IT knowledge required – you (or your IT provider) need to know how to manage Linux/Windows servers, firewalls, SSL, etc. - Time cost – compared to 3CX Hosted, which is “hands-off.” Difference from 3CX Hosted - Self-hosted = You run and manage everything yourself (more control, more work). - Hosted by 3CX = 3CX manages the server for you (less control, zero maintenance). 3CX Hosted - A fully managed cloud PBX: The 3CX system runs in the cloud (on 3CX’s servers), so you don’t need to worry about installing, maintaining, or updating the software. - Hosted directly by 3CX: Unlike self-hosting on AWS, Azure, or your own VPS, the infrastructure is owned and managed by the 3CX team. - Delivered as a service: You simply subscribe to a plan, and your phone system is ready to go.
