Frequently Asked PBX Questions

Will I completely control my PBX?

Yes, you will completely control the GUI of your PBX including but not limited to IVRs, Greetings, Call Flow, Extensions, Users, you name it!

Do I have root access?

Great question, the simple answer is no. We do not provide root access or shell access to any hosted PBX to maintain the integrity of our services in our datacenters.

Is there a VPN to my PBX?

No, we do not provide VPNs on vanilla installations of our Hosted PBX and it is not necessary. You will have TLS connectivity available for remote locations.

Do I have any access to the CLI?

Yes, you have access to run commands via the GUI that are CLI driven. This access is not via a shell prompt. This includes Real-Time Logging of the PBX to monitor activity that would otherwise be in the command line only.

Is there a limit to the number of extensions I can have?

No there is no physical limit however in a virtual Hosted PBX the limits are based on overall usage. You might have 35 extensions but only use 5-10 at a time.

If you used 50 extensions all day long you might consider a Physical QuBePBX hosted service which can support about 1000+ extensions based on the server configuration.

Do I pay per extension?

Definitely not! Many companies have a multitude of unused extensions. Kitchens, break rooms, empty offices, etc. You only pay for usage on your account, not the extension or features.


Am I able to configure a backup?

Yes, you can control the backup process and even move it to an offsite FTP Server. 

Do I have to pay for more features?

No, all available features are always included in your hosted product. The only difference in prices is a virtual server versus a physical server.
