Avaya Phone Systems

Premise-based and hybrid unified communications solutions

Considering an upgrade for your business phones?

Your phone system keeps your business moving, and when something breaks or falls short, you feel it immediately.

Teltek maintains Avaya-certified engineers, stocks a wide inventory of replacement parts, and supports Avaya customers across Maryland and DC under customizable maintenance plans, remote and onsite.

Because we know Avaya inside and out, we also make migration smoother than starting from scratch. When you're ready to move to SIP trunking or a cloud-based UCaaS platform, Teltek imports your call flows, users, and menu prompts so your team hits the ground running, not starting over.

Here's how we make the migration easier:

Avaya configuration review — we document and import your call flows, menu prompts, users, and call center features so nothing gets left behind

Strategic planning and coordination — migration on your timeline, built around your operations

Reliable internet for VoIP — we assess and recommend redundant internet providers before the first call goes over the new system

Technical support throughout — your Avaya system stays fully supported before and during the transition, nothing goes dark mid-migration

Parallel operation — Avaya and UCaaS run side by side during the transition so your team never loses a call.

Customized training — we bridge the gap between what your team knows on Avaya and how the new system works, so day one feels familiar

A Note on Avaya OneCloud

Avaya OneCloud —the RingCentral-partnered cloud platform —was discontinued when Avaya went through bankruptcy restructuring in 2023. If you were on OneCloud or planning to move there, Teltek can help you evaluate current cloud alternatives including MyCloud UcaaS and Microsoft Teams Voice, both of which deliver what OneCloud promised.

Avaya Legacy Models Still Support

Avaya Partner Advanced Communication System (ACS)

Since 1997, the Partner ACS became one of the most widely deployed small business phone systems ever made, nearly 2 million installed worldwide. Up to 21 incoming lines, 44 extensions, voicemail, on-hold music, intercom, overhead paging, and a reliability record that kept it running in Maryland offices long past its intended lifecycle. Teltek still stocks parts and supports it. But if you're still on Partner ACS, the honest conversation is about what happens next, and we're ready to have it.

Merlin Magix, Merlin Legend, and Merlin Classic

Built to last, which is exactly the problem. Merlin systems are still running in Maryland offices that installed them in the 90s. Parts exist, support is possible, but the longer you wait the narrower your options get. Teltek has seen every variation and can help you plan the transition before the system makes the decision for you.

When is it time to upgrade your business communications?

Here are some signs to watch for:

Outdated Equipment

Your desk phone is becoming obsolete, making it harder to complete system maintenance, find replacement parts, get support, or integrate new features you need.

Lacking Cost Saving Features

Can’t access new features and capabilities that would streamline systems, improve internal communication, and save your team time and/or money.

Poor Quality for Your Customers

Poor call quality, making communication difficult and negatively impacting the customer experience.

Growth Limitations

You can’t scale your system. In other words, your current business phone system is at max capacity, with no option for growth across a new location or expanded office space.

Reliability Issues

Frequent outages make it hard to do business and reliably receive incoming calls from clients and contacts.

Missing Remote Access Tools

You can’t support remote workers or remote access.

Looking for More Value

Phone costs keep climbing, but you aren’t gaining any new functionality or benefits.
