Plug-and-play desk phones: Grandstream IP phones, pre-configured by us

Order a Grandstream desk phone from NumberGroup and it arrives ready to use — pre-provisioned to your account. Plug in the power and an Ethernet cable to your broadband, and it works. No setup, no web UI, no IT person.

The easiest way to get a desk phone working with NumberGroup is to let us send you one that's already set up. Order a Grandstream IP phone from us and it arrives pre-configured to your account — no settings to type in, no web pages to log into, no IT person required.

How it works

When your phone arrives, there are just two things to plug in:

  • The power adapter we supply in the box
  • An Ethernet cable into your broadband router

That's it. The phone connects to us on its own and registers itself — you'll have a dial tone and be ready to make and take calls within a minute or two. Nothing to configure at your end.

The range

Three models cover almost every setup — entry, mid-range and executive. Members buy them at the price we pay our distributor, with no markup.
