Reading time: 5 minutes

The Asterisk open-source PBX is well familiar to seasoned IT professionals and has been trusted by many businesses to improve the efficiency of voice calls and a wide range of other useful features.

Understanding the Asterisk PBX System vs. the OMICall Virtual PBX System

What are the Asterisk PBX system and the OMICall system?

The Asterisk open-source PBX is an open-source software that provides enterprise telephony system capabilities. The Asterisk PBX system serves as the core of a cloud-based business VoIP system with easy IP PBX integration, featuring many complex interconnected IP PBX functions. However, Asterisk software is better suited for technology research and development, and appears to be not quite ready for direct business application.

The OMICall virtual PBX system, on the other hand, is a newer cloud-based platform designed specifically for business use as an intelligent customer care virtual call center. It helps businesses reduce voice communication costs, optimize operations, increase call answer rates, offers ease of use, and can be easily integrated with other systems.

Pros and Cons: OMICall Virtual PBX vs. Asterisk Open-Source PBX

	Asterisk Open-Source PBX	OMICall Virtual PBX System
Pros	– Open-source software that saves on development and licensing costs.	– Operates entirely on a cloud computing platform with integrated CRM customer management features.
	– IT and telecommunications teams can build their own IP-PBX system.	– Low cost: No charges for inter-provincial or international calls.
		– Easy to scale without hardware upgrades.
		– Effortless regional call forwarding.
		– Unlimited number of IP phones (SIP-based).
		– Easy monitoring and management via a web-based admin panel.
		– Saves staffing resources through automation: Auto-answer (IVR), Automatic Call Distribution (ACD), Voicemail, and more.
Cons	– Asterisk only runs on Unix-based operating systems, making installation and configuration of servers and workstations more complex than traditional PBX systems.	– Call quality is highly dependent on internet connection speed, as a fixed bandwidth must be dedicated to voice — simultaneous connections can degrade call quality compared to older technologies.
	– The security of the Asterisk open-source PBX is relatively low, as the server is built on a single computer.	– Being cloud-based and reliant on an internet connection, occasional line noise or echo may occur.
	– Asterisk is well-suited for technology research and development, but appears not quite appropriate for business application.	– Virtual PBX systems from some providers may be vulnerable to hacking and security breaches.
		– Assets are not physically located at the company’s headquarters and cannot be touched, seen, or physically measured.
