NBXGeeks are exceptional at what they do…

They installed an efficient and user-friendly phone system in our synagogue. They listened to our needs and has provided a phenomenal product with excellent responsive support (you will speak to a real live human who knows what they're doing!).
I highly recommend NBXGeeks.

NBX tech support reviews

We are the right fit
for any problem level

Small NBX tech support

Small Issue

The issue is for development, extension, or non-critical request. Issues that do not affect the functionality of the phone system or data networks.

Medium NBX tech support

Medium Issue

The customer is still in service, but the infrastructure is damaged. Timely measures should be taken. Half or more phones are down. Voicemail, reception phone, and apps are not available.

Urgent NBX tech support

Urgent Issue

Phone system disconnection. Extreme sway on business. The phone system is completely disabled, calls to the main one remain unanswered.

Frequently Asked Questions

Do I need to purchase NBX Phone Licenses along with the NBX Phones?

Sometimes, and it depends on the 3000 series phone you want to use on your IP 3Com phone system.

How much Voicemail is included in the NBX V3000?

An NBX V3000 system can support up to 48 simultaneous VTL connections.

How many NBX devices can the NBX V3000 support?

The V3000 can support up to 1500 devices.
What Counts Toward the Total Device Limit?
The total device count on an NBX system includes physical devices and certain software applications:

  • Physical Devices – Each NBX telephone, each channel on a Digital Line Card, and each port on an Analog Line Card counts as one device. Additional physical device limits are listed in the table later in this topic.
  • Software “Devices” (Applications) – The NBX Media Driver application counts as one device. Each installation (client) of the pcXset Soft Telephone application counts as one device.

What Does NOT Count Toward the Total Device Limit?
The NBX systems do not count most applications toward the total device limit, although some may be governed by license limits. Examples: voice mail ports, automated attendant ports, Call Park zones, System Speed Dials, and any other item with “None” in the second column…

Is the NBX V3000 Compatible with my existing NBX hardware and software?

Yes, and we can customize a solution for you to use existing 3Com IP phone equipment.

They saved us so much time and money
over the last 10 years…

We tried working with different companies and finally found NBXGeeks. At first, we thought the entire process of updating our phone system is going to be difficult and expensive, but they made everything easy and support is great… very importantly, the technology is always up to date and the price is affordable. Outstanding experience with this company. Highly recommended!
