We specialize in sales, service, installation and support of all new and refurbished AT&T / Lucent / Avaya equipment including telephones, accessories, telephone systems and voicemail systems. We are connectivity experts and understand the different electrical interfaces commonly in use and can interface the AT&T / Lucent / Avaya product line with just about any other brand of communications equipment.

We provide high quality maintenance for systems as small as a few phones all the way up to enterprise level communication systems. We get you running and keep you running with our experienced TIER 3 engineers and technicians. Eliminate the middle-man and save.

Why wait for your current provider to send inexperienced technicians out to fix your problems? If you currently have maintenance through an insurance company, call them and make us your preferred provider! Just let your sales representative know that you want High Reliability Systems to handle all of your maintenance issues. We offer direct billing to insurance companies such as UAC.
