Best VoIP and Telephony Certifications

VoIP certifications

Network convergence, in which a single network supports telephone, video, and data communication services, has resulted in immense changes to voice and telephony technologies over the last decade.

Corporate voice and telephony services are rapidly transforming from traditional public-switched telephone networks (PSTNs) and private branch exchanges (PBXs) to voice over IP (VoIP) and IP PBXs, often combined with digital faxing, videoconferencing, instant messaging and mobile communications. That means VoIP and telephony certifications now focus on digital communications, along with a good measure of IP networking protocols and methods to support such traffic and to control service quality.

In this article, we feature five solid VoIP and telephony certifications from Avaya, Certification Partners, Cisco, Digium (Asterisk) and Microsoft. Unified communications cover a lot of voice and telephony ground, and it adds video and other solutions to the mix as well.

Salary is a significant consideration when deciding whether to pursue a VoIP and telephony certification. SimplyHired lists $108,184 as the average salary for a VoIP engineer, although Glassdoor's average for a VoIP engineer is somewhat lower at $83,772. Still, a salary just less than $85,000 is a worthwhile goal in the industry, with a good growth path into more senior positions readily attainable.

To help determine our top five VoIP and telephony certifications, we performed an informal job board survey. That data indicates the number of job posts in which our featured certifications were mentioned on one specific day. The data should give you an idea of the relative popularity of each certification.

Avaya is one of the leading solution providers of business communications and collaboration systems. As a spinoff of Lucent Technologies, itself an offspring of Bell Labs, Avaya's roots are firmly planted in telephony.

Individuals not affiliated with a specific organization can create a "non-relationship" account on the Avaya Learning site to purchase a certification exam.

The vendor-neutral CTP certification was developed by Certification Partners and the Telecommunications Industry Association (TIA). It’s also endorsed by industry leaders such as Cisco, Avaya, Mitel, Toshiba and Vertical. Many of these leaders either accept the CTP as a stepping stone or prerequisite to their credential programs or recommend the CTP for training and preparation. Certification Partners maintains a complete list of endorsements from telecommunication leaders.

The CTP requires the successful completion of one exam that focuses on methods, concepts and best practices in the following areas:

  • Data and Internet Protocol (IP) networking for convergent networks
  • Voice and telephony services, functions and technologies
  • Convergence technologies

Certification Partners also offers the Convergent Network Technologies (CCNT) certification, which aims at professionals who sell and support convergence services, as well as the CIW certifications in networking and security, web technologies and design and development. Candidates interested in working in the field of convergence who do not yet possess the requisite experience are advised to first obtain the CCNT credential and then gain the required experience.

Certification Partners does not require recertification to maintain the CTP.

Since its humble beginnings as an open source project in 1999, Asterisk has grown exponentially and become a well-recognized and respected framework for communication and conference servers, VoIP gateways and IP PBX systems. Asterisk can be found in more than 170 countries, powering more than 2 million servers worldwide. Per Digium (which maintains Asterisk in conjunction with the Asterisk community), Asterisk is used by most of the Fortune 1000 companies.

With such widespread popularity, it's only natural that professionals with Asterisk skills are in demand. To meet industry needs, Digium offers several training courses (Asterisk EssentialsFast Start and Advanced), as well as the Digium Certified Asterisk Professional (dCAP) and Digium Certified Asterisk Administrator (dCAA) certifications.

The dCAP targets experienced Asterisk professionals. Candidates are expected to possess real-world experience (typically a minimum of 3 to 24 months), in-depth knowledge of Linux (basic administration, manipulating files and modifying configuration files) and Asterisk experience (installation, Asterisk dial plan format and syntax, use of basic CLI commands and registration of VoIP devices). Other recommended skills include basic programming and scripting languages (Perl, Bash, C and/or C++, for example) and an understanding of VoIP protocols.

Candidates must pass a two-part exam, which consists of a written exam and a practical lab exam (in which you configure a PBX), to earn the credential. While there are no prerequisites, the Asterisk Advanced training course is highly recommended before attempting the exam.

Although the Digium website doesn't specify recertification requirements, dCAP certification is granted for a "specific released, stable version of Asterisk."

Certification Name

Digium Certified Asterisk Professional (dCAP)  

Prerequisites & Required Courses

None required. Asterisk Advanced training course highly recommended, along with 3 to 24 months of real-world experience, working knowledge of setting up and maintaining an Asterisk server, and familiarity with Asterisk sample configuration files. (Training costs approximately $1,995.)

Microsoft rolled out several new MCSE certifications in 2016, including the MCSE: Productivity. Although this certification is geared toward enterprise-grade hybrid and cloud solutions for Microsoft Office, it allows candidates to specialize in any of several Microsoft technologies, including Skype for Business.

To obtain the MCSE: Productivity credential, candidates must first obtain the Microsoft Certified Solutions Associate (MCSA): Office 365, MCSA: Windows Server 2012 or MCSA Windows Server 2016 certification. Then, they must pass an elective exam from an approved list. Currently, there are eight different exams to choose from. In addition, Microsoft recommends at least three years of experience.

The MCSE: Productivity credential doesn't expire. However, credential holders are encouraged to re-earn the certification each year by passing another elective exam. Doing so indicates your desire to stay current on technologies and broaden your skillset, and you'll post another entry to your certification transcript.
