My BIGGEST complaint is the complete lack of user reference material. Zultys has a small 4 page "Quick Reference" guide that basically gets you making phone calls and not much more. Our previous phone system had an excellent user guide that detailed every feature of that phone system. The only training we got was what we found on YouTube! I will say the audio quality is excellent. Navigation is buried and confusing. Again, wouldn't it be nice to have a detailed user guide! Another negative is their handsets. While they are sleek and pretty, they are slim, hard to hold and fragile. I purchased phone pads to compensate for this as my guys were complaining they were impossible to hold with their cheek and shoulders while talking on the phone and working on the PC. I suppose a work around for this would be headsets for everybody. This system is also prone to just dropping calls. Our fax machine still drops calls before the system transfers to hold before the fax machine picks up. Nobody seems to know how to fix this either. Needless to say we miss our old system.
Our company specialized in smaller "key system" units until we were approached by two 100+ user clients to provide system, installation and support services. After researching available VOIP PBX vendors solutions, Zultys was an easy choice. After several years and multiple deployments, Zultys remains the right choice. Zultys is amazingly open to dealer feedback and development in helping us to meet and exceed customer's expecations. Bill Rakowitz General Manager Ganado Telephone Company
I have been with OneSuite for over 18 yrs I have brought my modem with me for multiple overseas visits. I was able to make and receive calls with clarity and reliability. I used their smartphone app since 2015 when I got my first smartphone, until recent the implementation of 5G service when I had to get a new phone. For years I would buy a data SIM card when overseas and use the voip app through the data stream (this was before Wifi calling folks). it has worked beautifully. Thanks to Android software changes the app has not worked with any of my android 10 or 11 phones. (still works with my 2015 android). Incoming calls have always been free, out bound calls depends on the country your calling but has always been very low priced. This is still a small company, I think I have always spoken with the same customer service agent over the years. He has been great to work with, but they are overwhelmed much of the time because of the small staff. They are in process to upgrade their app but they did offer an alternative app to use in the meantime. If you are looking for an inexpensive way to have a voip line this is the one for you. Be sure to at least receive a few calls (I use an old fashioned message machine) within the use limit or they will shut off the account. I was able to get mine re-instated the couple of times I neglected the line.
We used OneSuite for years with no problems. Then we did not use it for a while because the person we used to call in another country died. We now have a new contact there, however OneSuite will not work and we cannot log in, getting the message that the account has expired. The documentation does not disclose that they will keep your money if you don't use the service for 6 months.
