Phone Services

What exactly is an "extension" and how does that differ from my phone number/s

ZTelco's phone service is quite different from traditional phone service, and everything revolves around extensions. In order to operate on ZTelco's phone system, individual telephones must have a virtual identity, known as an extension, that a phone is programmed to utilize. The extension may also have custom programming to accommodate the user it is assigned to, like the ability to reach a user’s cell-phone if they do not answer their desk phone. The extension numbers themselves can also be dialed "internally" so that extensions on the same phone server may dial one another without using up any of your inbound / outbound capacity.

What are my options when it comes to phone call routing?
Does ZTelco allow international calling?
What kinds of phones does ZTelco recommend? What kind of phones work on ZTelco service?
I would like to be able to manage my own phone-service, with ZTelco Hosted PBX service, will I be able to administer my own phone behaviors?


Is this satellite service?

No, we install a non-penetrating, fixed microwave radio tower on top your building and sync it with another nearby radio tower. The two radios talk to one another and transmit data wirelessly.
