Mitel Software Assurance and Support
Mitel Software Assurance and Support services play an important role in helping your Mitel solution remain current and insures CDN has the manufacturer support needed for critical failures.  If a problem resolution requires Mitel support and your system is not under Software Assurance, Mitel will not provide CDN technical support of any sort, if you are not enlisted in the Software Assurance Program.  Mitel will require you to upgrade and enroll in Software Assurance at that time with a re-enrollment fee which can be costly. Protect your investment and remain enrolled in the program always. Learn more about why Mitel Software Assurance and Support is important to your business by watching the video below.
