What are the benefits of Cloud One Telephony Solutions?

  • Easily make adds, moves, and changes to the phone system as needed
  • Employees have more ways to stay connected and customers can reach them more easily
  • Take all of your phone system’s features with you for use at home, at the office, or on the road

What equipment do I need to use Cloud One Telephony Solutions?

All you need is a broadband Internet connection.

  • You will manage your phone system via the Cloud One Phone system web interface.
  • Client App is free of charge, it can be downloaded and installed on your mobile and PC.
  • You can also provision an IP phone for each of your users.
  • However, a premium quality router is preferred, a low-end router tends to have glitches from time to time. 


How is the call quality of Cloud One Telephony Service & Solutions? 

The call quality of cloud communications systems depends on the speed and reliability of your internet.

You will hear a vast improvement in call quality compared to traditional landlines. VoIP calls achieve this through HD Voice technology.

However, you need to make sure you have sufficient bandwidth to make high-quality VoIP calls. If you feel as if the quality of your calls is lacking, you can adjust your quality of service settings on your router. Most routers allow you to prioritize voice calls on your data network, which prevents other applications from affecting the call quality. If you’re not sure whether your router has this capability, contact your Internet Service Provider for more information


Are calls on Cloud One Telephony Service & Solutions secure?

Cloud One Telephony Solution is an application-level tunneling service; it only handles SIP data and the custom protocol data of the Client APP and does not touch the PBX data, which means no party can access the PBX through the tunneling server.

All transmission between the PBX and the tunneling server is encrypted. And each PBX will have its own encryption key. Even if the tunneling server is brought down by a hacker, there is no way to replace the tunneling service and get original transmission data since the hacker does not know the encryption method.

The tunneling server is secure and has multiple protection measures. Our support team stands by to handle any emergency in no time.

Cloud One Telephony Service will whitelist your on-premise ISP static public IP address on our central firewall to allow traffic from only your location. It is Mandatory to inform Cloud One every time on your new or change of ISP static public IP or DDNS hostname for whitelisting on Cloud One's Central firewall. Failure to inform Cloud One may result in your connection getting blacklisted on our network & service becoming unavailable.


Will Cloud One Telephony Service & Solution continue to work even if I move offices?

Yes, as long as you have fast and reliable internet at your new location and you have informed Cloud One support on your new IP address, Cloud One Telephony Service & Solution will work.

Since your Cloud One Telephony Service & Solution operates in the cloud, it’s not tethered to a physical location.


If I lose power, will I still be able to make phone calls with Cloud One Telephony Service ?

In most cases, you will not be able to connect calls if there’s a power outage in your premise. Our Cloud Telephony Solutions works over the internet. During a power outage, your router will not be able to function, which means there will be no internet access.

The first exception to this is if you have a backup power source that could power the router (and therefore maintain your internet connection). If you use Power over Ethernet (PoE), that may need backup power as well.

The second exception to this is if you have 4G/5G connection on your laptop or Mobile phone, simply switch to 4G/5G and Client APP will automatically connect again.
