VoIP products and services for micro-enterprises

If you’re looking to grow your business, consider serving micro-enterprises with 1-20 employees. According to the Census Bureau’s Annual Survey of Entrepreneurs, firms with between 1-20 employees made up 89% of all U.S. firms in 2016. While this has traditionally been an underserved market when it comes to VoIP telecommunications, more and more equipment manufacturers are offering products tailored to their needs. In this article, we review some cutting-edge devices that are ideal for micro-enterprises.

Financing plans and service contracts

With leasing and DaaS (device as a service or equipment rental) programs, customers can acquire IP PBXs, telephones, and other equipment without any up-front capital outlay, and they can account for their equipment lease or rental payments as operating expenses. Click here for more information about our leasing programs, and here for more information about our DaaS program. Check with your TeleDynamics rep regarding which equipment is eligible for these programs.

Installing an on-premise system for your customers also allows you to offer your own service contract that guarantees product firmware upgrades. The idea is to get a contract that allows some sort of yearly renewal to keep you actively involved in upgrading and working with the system after installation. This keeps you in the loop as the customer’s needs evolve and they need to add new phones, purchase new licenses, change a voicemail prompt, etc. As more software is introduced into business telephone systems, firmware upgrades allow your customers to keep up with any new releases and emerging technology.


Of course, small businesses can also procure VoIP telephony service from an Internet Telephony Service Provider (ITSP). In this case, the ITSP (rather than your company) takes care of all the equipment maintenance and upgrades. If your customer would like to sign up with an ITSP, TeleDynamics has a number of partners we can recommend.

IP PBXs for micro-enterprises

On-premise IP PBXs are a growing trend among small and micro-enterprises. IP PBXs are becoming increasingly intuitive to manage and economical to acquire.

Grandstream UCM6202 IP PBXGrandstream’s UCM6202 IP PBX has a robust feature set that can scale with growing businesses. It can handle up to 500 users, 50 SIP trunks and up to 50 concurrent calls, all at a price point that is quite accessible for businesses with fewer than 20 employees. It also allows you to connect Grandstream endpoints with zero configuration (plug and play). The UCM6202 comes with 2 FXO and 2 FXS ports for connecting the VoIP phone system with the PSTN, as well as for connecting analog devices like fax machines.

Yeastar S20 IP PBXYeastar’s S20 IP PBX supports 20 SIP trunks, 50 users and up to 10 concurrent calls. With the Yeastar S-Series, all the telephony interfaces are modular and customizable, whether it’s FXS, FXO, ISDN BRI, GSM/3G, or E1/T1/PRI. The S20 has 2 onboard module slots, which support up to 4 FXS/FXO/BRI ports and up to 1 GSM/3G/4G channel, depending on the modules used.

Yeastar S412 IP PBXFor even more customization, Yeastar’s S412 IP PBX is another robust device for small offices. It supports 8 SIP trunks, 8 users and 4 concurrent calls.
