Since 2001, Zultys has become a trailblazer in lightning-fast telephone service. This is thanks in part to its innovative approach to Voice over Internet Protocol (VoIP) phone systems. Instead of being tied to a landline, the IP phone system can make phone calls through the internet.

VoIP phones get rid of landline and data costs. Instead, both are combined into one easy-to-manage package that only increases in value. It is a great way to replace an old landline for your business.

If you do not want an VoIP phone, Zultys has products that fit your needs. Handset phone units that connect to a landline are also ready from Zultys, allowing you to use your system with the enhanced features for which the company is known.

Zultys can also provide mobile phones that offer instant messaging and full connectivity to cellular networks. In addition, Zultys offers their patented Presence system that allows for you to know the location of your employees. Zultys mobile phones can also hop onto an IP PBX system to prevent more costs from piling on.


Avaya’s phone services work with a wonderful program known as the IP Office™ Platform. You have full functionality of your phone systems via your landlines, cordless, or mobile phones within your company.

IP Office can use up to 1,000 users at 32 different locations. Together, they have access to all of your company’s media and voice platforms. This allows for your conversation to migrate from the phone to the computer. Instead of being tethered to one form of media, combine your services with IP Office.

IP Office also allows for full communication on any desktops or laptops. This includes video calls, teleconferencing, or even just a phone call. Telephone Connection, along with Avaya, wants to provide you with a tool that will let your business keep going no matter the form of your communication.

Interested in an IP Office? TC Tech Systems offers not only a traditional onsite IP Office but also a Virtual IP Office. With the Virtual IP Office, pay a small monthly fee only for the phones you need. The monthly fee includes the service, maintenance, and long distance without equipment to purchase or maintain. Contact us to discuss which IP Office solution is right for your company.
