What Is Avaya IP Office?
Avaya IP Office is a modular unified communications platform built for small and medium-sized businesses, from single location offices to multi-site companies with branch and head office locations. It bundles telephony, voicemail, conferencing, and messaging into one system, and it can be deployed on-premises, in a hybrid configuration, or extended to remote and mobile employees through Avaya’s software clients. At the core of most Charlotte-area installations is the IP Office 500 V2 control unit, which supports a mix of analog, digital, and IP telephones and can scale through add-on expansion modules. Depending on how it’s configured, an IP Office 500 V2 system can grow to support several hundred extensions and a mix of trunk types, including traditional analog lines, T1/PRI digital circuits, and SIP trunks that carry calls over the internet. That flexibility is part of why IP Office has stayed popular with growing businesses for so long — you are rarely locked into a single way of connecting to the outside world. IP Office also includes administrative tools for managing the system (Manager), tracking call activity (SMDR reporting), and monitoring system health, along with an auto attendant that routes callers to the right person or department without tying up a receptionist.

Avaya J100 Series Desk Phones
If your IP Office system needs new handsets, Avaya’s current lineup is the J100 Series, which has largely replaced the older 1600 and 9600 Series phones still sitting on many Charlotte office desks today. The J100 Series includes several models built for different roles inside a business:
- J129 – an entry-level, single-line phone with a monochrome display, a good fit for lobbies, break rooms, or common-area phones

- J139 and J159 – color-display models with additional programmable line and feature keys for everyday office use
- J169 and J179 – larger color touchscreen phones with Gigabit Ethernet ports, built for receptionists, managers, and higher call volumes
- J189 – the top-of-line model, adding USB connectivity and Bluetooth support for headsets, aimed at executive offices and conference rooms
All of the J100 Series phones are backward-compatible with existing IP Office systems, so in most cases we can add or replace handsets without touching your control unit or your wiring. Click to Call 704-729-7210 or visit our contact us page.
Avaya 9600 and 1600 Series IP Deskphones
Before the J100 Series, Avaya’s standard desk phone lineup was the 9600 Series (marketed as the one-X Deskphone Edition) and the 1600 Series. The 9600 Series includes models like the 9608, 9611G, 9620, 9630, 9640, 9650, and 9670G, along with the SIP-only 9601, and it works with both the Avaya Aura platform and IP Office. The 1600 Series — the 1603, 1608, and 1616 — was the simpler, more budget-friendly line built for IP Office R4.2 and later. Both series are well built and still show up all over Charlotte offices, and we keep parts and refurbished units on hand to service or expand these systems for as long as it makes financial sense to do so.

Avaya Workplace Client: Take Your Extension Anywhere
For employees who split time between the office, home, and the road, Avaya offers Workplace Client, a software phone app for Windows, Mac, iOS, and Android. Once it’s set up, Workplace Client lets an employee make and receive calls on their normal business extension from a laptop or smartphone, join video meetings, and message coworkers — all tied back to the same Charlotte-based IP Office system running at your office. It’s a practical option for hybrid teams, multi-location businesses, or anyone who needs their office number to follow them without carrying a second phone.
Avaya Vantage Devices: Touchscreen Communicators
For businesses that want more than a standard desk phone, Avaya also makes the Vantage line of Android-based touchscreen devices, including the K155, a compact 5-inch model with a physical dial pad, and the K175, an 8-inch touchscreen device with a built-in camera for video calls (the earlier K165 model has since been discontinued by Avaya). Vantage devices put one-touch voice, video, and chat access on the desktop, and they’re a popular fit for conference rooms, reception areas, and healthcare or hospitality settings where a simple touchscreen interface matters more than a full keypad.
Considering a Move to the Cloud? Avaya Cloud Office
Not every business wants to keep owning and maintaining phone system hardware indefinitely. For Charlotte business es exploring a fully hosted alternative, Avaya also offers Avaya Cloud Office, a cloud-based unified communications service positioned as a migration path for existing IP Office customers. It moves the phone system itself off your premises and into the cloud, in exchange for a predictable monthly cost and less hardware to manage on-site. A cloud move isn’t the right call for every business, and we’re glad to walk through the tradeoffs against sticking with, expanding, or repairing your current IP Office system before you decide anything.
Still Running an Older Avaya System?
Plenty of Charlotte businesses are still running Avaya IP Office 500 or IP Office 500 V2 systems, or even older Avaya digital and analog platforms, paired with 1600 or 9600 Series handsets. We service and support these existing installations, including repairs, moves, adds, and changes, and adding compatible new handsets when old ones fail. To be upfront about it, DS1 Phone Systems is not an authorized Avaya dealer — we’re an authorized dealer for NEC and ESI phone systems — but we have serviced Avaya equipment already in place for Charlotte businesses for many years. If your system is on its last leg, we’ll give you an honest read on whether a repair, an expansion, or a move to a new NEC, ESI, or hosted VoIP system makes more financial sense, with no pressure either way.
Still Relying on a PARTNER System?
Long before Avaya IP Office and the J100 Series, many small Charlotte businesses ran their phones on Avaya’s PARTNER and PARTNER ACS systems, digital key telephone platforms that trace back to Avaya’s Lucent and AT&T roots. Depending on how it was configured, a typical PARTNER ACS system supports somewhere between roughly 14 and 33 lines and extensions, along with Partner Messaging voicemail, auto attendant with sub-menus, direct station select and busy lamp field buttons, and one-number reachability that can ring a cell phone when a desk call goes unanswered. These systems were built to last, and plenty are still running reliably in Charlotte offices today — but Avaya stopped manufacturing PARTNER hardware years ago, so replacement phones, carriers, and voicemail modules are only getting harder to find. If your PARTNER or PARTNER ACS system is starting to show its age, call 704-729-7210 or visit our contact us page, and we’ll help you sort out whether a repair, a used replacement part, or a move to a modern phone system makes the most sense for your business.
Avaya PARTNER Phones: 6D, 18D, and 34D Handsets
Avaya PARTNER and PARTNER ACS systems in Charlotte were paired with a handful of well-known digital phone models, and plenty of them are still in daily use today. The Avaya PARTNER 6D is the compact option, with a two-line by sixteen-character backlit display, a two-way speakerphone, two intercom buttons, and four programmable line and feature buttons — a practical fit for a back office or a lightly used desk. The Avaya PARTNER 18D is the workhorse of the lineup, offering sixteen programmable buttons with dual-color status LEDs, a two-line by twenty-four-character backlit tilt display, and built-in conference, transfer, and hold keys, and it’s the handset you’ll find on most desks running a PARTNER ACS system. The Avaya PARTNER 34D steps up further with thirty-six programmable buttons and ten fixed feature buttons, including two dedicated intercom keys, and is typically reserved for receptionists, office managers, or anyone handling a high volume of calls and transfers. We keep refurbished PARTNER 6D, 18D, and 34D phones on hand for Charlotte businesses that need a working replacement handset without ripping out an otherwise functional PARTNER ACS system. Call 704-729-7210 or visit our contact us page if you need a replacement PARTNER phone or want an honest read on your options.
Avaya Merlin and Merlin Magix: Another Legacy Platform We Support
Alongside the PARTNER systems, Avaya’s Merlin and Merlin Magix platforms were another common choice for small and mid-sized Charlotte businesses back in the Lucent and AT&T era. Merlin Magix in particular could scale up to roughly 200 extensions and 80 central office trunk jacks, with multi-site networking, centralized voicemail, and basic call queuing built in, using the 4400-series digital phones. Like the PARTNER line, Merlin and Merlin Magix hardware hasn’t been manufactured in years, so parts availability keeps shrinking. If you’re still running a Merlin or Merlin Magix system, call 704-729-7210 or visit our contact us page, and we’ll help you weigh keeping it running against moving to something newer.
Avaya Definity and Avaya Aura Communication Manager
On the larger end of the Avaya lineup are the Definity PBX and its modern successor, Avaya Aura Communication Manager, enterprise-class platforms built for large organizations, healthcare systems, and multi-site call centers, with a single Aura system capable of scaling into the tens of thousands of users. These are a different class of system than the small-business platforms most Charlotte offices run, and supporting them well typically calls for a specialized enterprise engineering team. If your business has a Definity or Avaya Aura deployment, we’re glad to point you toward the right resource, or to talk through whether a smaller platform like IP Office fits your business better going forward.
