If it is not installed and programmed properly and you don’t know how to use it, then you will never be satisfied. Training is provided during the installation process so that when we leave everyone at your company knows how to use the system. Also, we offer unlimited user and administrator training for 30 days after the installation.

This will enhance your day-to-day communications with these advanced capabilities. Call us to discuss how this can benefit your company.

Call accounting

Many new business phone systems today have built-in call accounting services or provide a data port from which the data can be captured. We offer various accounting software packages which allow manipulation of this data for your use. Contact us and we can discuss your specific needs.

Professional on hold and auto attendant recordings

Biz ReTek offers telephone equipment with either built-in storage for information on hold or external playback devices that use CD’s or FOB’s. We work with a professional recording specialist who will develop a info on hold script with background music to suit your specific needs. As always, let us know your needs and we will be glad to assist you.


Contact us to discuss your specific conferencing needs and we can recommend the best solution from using the business phone system to subscribing to one of our conferencing services.

Remote Administration

Many companies today do not have a full time IT staff or even a part time telephone system administrator which makes remote administration one of the most valuable technologies available today. This allows Biz ReTek to remotely perform many tasks for you including making programming changes, do diagnostics , perform normal system software upgrades and back-up the systems database so that it can be restored in the unlikely event of a system failure. If you have a maintenance contract we do all of this for free.
