Simple guide to difference between hosted pbx and sip trunking terms:

What is Hosted PBX?

A hosted PBX (Private Branch Exchange) is a cloud-based phone system that transforms business communications by being managed offsite by a third-party provider. This setup removes the need for companies to invest in physical infrastructure. Calls are made over the internet using VoIP technology and the SIP protocol, seamlessly connecting to the Public Switched Telephone Network (PSTN).

Benefits of Hosted PBX

  1. Quick Deployment: Setting up a hosted PBX system is fast and straightforward. Businesses can often get started within a day, requiring only IP phones or softphones and a stable internet connection.

  2. Cost Savings: With no need for on-premise hardware, businesses save significantly on setup and maintenance costs. The provider handles all equipment and software updates.

  3. Maintenance-Free: The hosted PBX provider manages all maintenance, including software updates and system upgrades, freeing businesses from technical hassles.

  4. Scalability: Hosted PBX systems are highly scalable, allowing businesses to easily add or remove users as needed without significant investment.

  5. Geographical Flexibility: Employees can access the phone system from anywhere, thanks to features like webphones and mobile apps. This flexibility supports remote work and travel.

  6. Advanced Features: Hosted PBX offers a range of sophisticated features, including call forwarding, voicemail hosting, auto attendants, and conference calling.

Drawbacks of Hosted PBX

  1. Internet Dependency: Since hosted PBX relies on internet connectivity, any network issues can affect call quality and availability.

  2. Audio Quality Issues: Call quality can suffer due to poor internet connections, experiencing issues like jitter and packet loss.

  3. Limited Customization: Hosted PBX systems offer less customization compared to on-premise solutions, limiting the ability to tailor features to specific business needs.

  4. Security Concerns: The security of a hosted PBX system largely depends on the provider’s protocols. Businesses must choose providers with robust security measures to protect their communications.

Hosted PBX is an attractive option for businesses seeking a flexible, cost-effective, and feature-rich phone system. However, understanding potential drawbacks is crucial for making an informed decision.

What is SIP Trunking?

SIP trunking is a modern telecommunication solution that connects on-premise PBX systems to the internet, allowing businesses to make and receive calls over a VoIP service. Unlike hosted PBX, which is entirely cloud-based, SIP trunking requires some existing hardware and setup on the business’s premises.

  3. Video Conferencing: With SIP trunking, video conferencing becomes seamless, allowing businesses to hold virtual meetings without additional infrastructure.

  4. Data Exchange: SIP trunks can carry not just voice but also video, email, and other data types, facilitating smooth and integrated communication across various platforms.

  5. Business Continuity: SIP trunking supports business continuity by enabling call rerouting and failover options, ensuring that communication remains uninterrupted even during outages.

Drawbacks of SIP Trunking

  1. Complex Setup: Implementing SIP trunking can be complex, requiring configuration of SIP endpoints and integration with existing PBX systems. This often necessitates skilled IT staff to manage the setup.

  2. Troubleshooting Difficulties: Identifying and resolving call quality or connectivity issues can be challenging, often requiring specialized networking knowledge.

  3. Emergency Calling Issues: Properly configuring emergency calling (e.g., 911 services) over SIP trunks can be complicated, and misconfigurations are common.

  4. Provider Dependence: Businesses rely on their SIP provider for connectivity. If the provider experiences an outage, communication can be disrupted unless there are backup systems in place.

Key Differences Between Hosted PBX and SIP Trunking

Initial Costs

When choosing between Hosted PBX and SIP Trunking, the initial costs can be a deciding factor.

With Hosted PBX, the startup costs are generally lower because the service provider manages the infrastructure. This means you won’t need to invest heavily in hardware. Instead, you pay for IP phones and a reliable internet connection.

In contrast, SIP Trunking requires a more substantial initial investment if you don’t already have an on-premise PBX system. You’ll need compatible hardware and possibly upgrades to your existing PBX, which can increase costs.

Ongoing Fees

Ongoing fees also differ significantly between the two options.

Hosted PBX usually involves monthly fees based on the number of users. These fees can range from $15 to $50 per phone line, depending on the features and services included.

For SIP Trunking, fees are often based on the number of channels (equivalent to phone lines) you need. This can provide cost savings for businesses with high call volumes but may require more careful management of usage charges.

Maintenance and Management

Maintenance is another area where these systems diverge.

With Hosted PBX, the provider handles all system updates and troubleshooting, freeing your IT staff from these tasks. You simply manage user settings and preferences.

SIP Trunking, however, requires more involvement from your IT team. They need to oversee software updates and handle any troubleshooting, which can be resource-intensive.

Geographical Flexibility

Hosted PBX offers excellent geographical flexibility. Employees can access the system remotely using softphones or mobile apps, making it ideal for remote work environments.

SIP Trunking can also support remote access but typically requires more complex configurations, such as multi-node registrations, to achieve the same level of flexibility.

Call Quality

Call quality is critical for any business communication system.

Hosted PBX relies on your internet connection, which can lead to variability in call quality. Providers often use public internet routes, which can affect performance.

SIP Trunking can offer better call quality if you use a private IP network or dedicate lines specifically for voice traffic. This setup can provide more control over call quality.

Scalability

Scalability is a key advantage of Hosted PBX. It’s easy to add or remove users as needed, making it suitable for small businesses and those with fluctuating staffing levels.

SIP Trunking is also scalable but may require bandwidth adjustments to accommodate growth, especially for large companies with multiple locations.

Security

Security considerations differ between the two systems.

Hosted PBX security depends heavily on the provider’s measures. It’s crucial to ensure they have robust policies in place to protect your data.

SIP Trunking allows for more control over security since the infrastructure is on-premise. You can implement custom security protocols, but this requires a knowledgeable IT team.
