In telecommunications, businesses need Private Branch Exchange (PBX) systems to manage their internal and external communication. Without it, companies wouldn’t be able to operate. Staff would not be able to work. Customers may not be able to make inquiries. Data could get lost. This substantial disruption could result in a serious loss of trust. That’s why PBX systems play a critical role in staying connected and operational.
When it comes to choosing PBX solutions, businesses have two options: proprietary-based and open standard-based PBX systems. Let’s discuss what they are, their advantages and disadvantages, and how Kital provides a complete PBX phone system tailored to your business needs.
What is Open Standard-Based PBX?
An open standard-based PBX system is a telecommunication platform that operates on open protocols or open-source software, primarily the Session Initiation Protocol (SIP), which facilitates multimedia communication over the internet. It offers businesses the capability to customize, scale, and integrate their existing communication infrastructure without being limited to the vendor’s full ecosystem.
Unlike traditional proprietary PBX systems that rely on the hardware and software owned solely by the vendor, open standard systems allow businesses to use almost any SIP phone, gateway, or standard-based peripherals. Open standard-based PBXs can be deployed on-premises or hosted in the cloud, providing organizations with options that suit their operational needs. They support various communication channels, including Voice over IP (VoIP), video conferencing, and instant messaging.
Brands Offering Open Standard-Based PBX Systems
Open standard PBX systems comply with widely accepted industry standards that can be compatible with multiple vendors. Some of the most well-known open standard PBX brands include:
Asterisk
Asterisk is a free and open-source framework for building communications applications. It is widely used for its flexibility and extensive features.
Xorcom
Xorcom offers a range of products for small to medium-sized businesses seeking scalable communications. It streamlines switchboard protocols and helps employees work more efficiently behind the reception desk.

FreePBX
Another popular open-source option built on top of Asterisk, FreePBX provides an intuitive web interface for managing PBX features without requiring extensive technical knowledge.
Pros of Open Standard-Based PBX
Open standard PBX offers several advantages, making it an attractive option for businesses that need a customizable telecommunication solution. It allows businesses to innovate without the limitations of a proprietary PBX. Here are the key strengths of open standard PBX:
Cost Savings
Open standard-based PBX systems do not lock you into long-term service contracts or a costly total system overhaul. They can be a more cost-effective option in many business scenarios. These systems also typically have lower upfront costs because they do not require licensing fees. You can also explore more affordable alternatives without being forced to stick to a single vendor’s pricing.
Scalability
Since open standard PBX is not tied to specific hardware, businesses can modify their communication infrastructure without needing a complete system overhaul. For example, businesses can easily add new users or features to suit their needs. The best part is, there are no operational disruptions or significant costs. This adaptability is highly beneficial for growing businesses with changing needs and goals.

Interoperability
Open standard PBX supports a wide range of devices and applications due to their adherence to common protocols like SIP. It can easily be integrated with other standard-based telephony devices so that companies can still use their existing technologies while exploring new options.
No Vendor Lock-In
Perhaps the most valuable benefit of open standard PBX is independence from a single vendor. This means businesses can mix and match hardware and software from different providers. Businesses are also not confined by the manufacturer’s terms and conditions.
Cons of Open Standard-Based PBX
Despite their many advantages, open standard PBX also come with drawbacks:
Complex Setup and Management
Given that these systems are flexible and customizable, they can be more difficult to set up and maintain because they have various components. Businesses often need IT expertise to install, configure, and manage the entire system. Without the appropriate technical expertise in-house, companies may need a third party to assist them.
Security Risks
Open-source systems are more vulnerable to security threats due to the nature of their complexity and accessibility. Since the source code is open, it can potentially be exploited by hackers if not properly secured. To enhance security, businesses must invest in security measures such as firewalls and encryption.

Limited Vendor Support
Proprietary systems come with end-to-end support from the vendor. With open standard systems, businesses may need to consult external experts or community forums since they do not rely on a single vendor. This may delay the resolution of issues in some cases and cause downtime.
Versatile IP-PBX Phone System
When choosing the right system for your operations, consider factors such as technical expertise, support needs, and current communication infrastructure. By thoroughly assessing these factors, you can make more informed decisions with telephony solutions.
