If your Avaya phone system is off the air, it can bring business operations to a halt very quickly. Many Australian organisations still rely on Avaya PBX platforms that were deployed years ago and have performed reliably for a long time. However, changes in carrier networks, office locations, and internet infrastructure are now exposing weaknesses in older Avaya environments.
At BroadConnect, we help businesses troubleshoot Avaya phone systems, restore services quickly, and plan safe migrations when repairs are no longer the best option.
Why Avaya Phone Systems Go Offline
In most cases, an Avaya system does not fail on its own. Outages are usually triggered by external changes such as carrier migrations, firewall upgrades, or the move to the NBN. Older Avaya systems were commonly designed for ISDN or early SIP deployments, and these services are no longer supported by many providers.
When businesses transition to business NBN services without reconfiguring their Avaya environment, phones may stop registering, inbound calls may fail, or audio may drop in one direction. These symptoms often point to SIP compatibility or network prioritisation issues rather than handset faults.
Common Avaya PBX Problems We See
As Avaya systems age, hardware reliability becomes a growing concern. Control cards, power supplies, and expansion modules can degrade over time, resulting in random reboots or total system outages. Replacement parts are increasingly difficult to source, which extends downtime and increases costs.
Another challenge is network integration. Avaya PBX systems are sensitive to firewall rules and NAT configurations. Even small router changes can interrupt connectivity with SIP trunking services, causing calls to fail or ring intermittently.
For businesses that have adopted hybrid or remote work, Avaya’s limited flexibility can also become an issue. Legacy systems were never designed to support mobile users and cloud collaboration tools in the way modern businesses now expect.
Before You Replace Your Avaya System
Not every Avaya issue requires a full replacement. In many cases, outages can be resolved by correcting network settings, upgrading firmware, or aligning the phone system with the correct carrier service.
Ensuring your voice traffic runs over a stable business internet connection is critical. Consumer-grade internet often lacks the consistency required for real-time voice, which can make an Avaya system appear unreliable when the root cause is connectivity.
BroadConnect can assess whether your existing Avaya system can be stabilised or whether ongoing fixes will continue to cost more than they’re worth.
We have worked with BroadConnect for several years now and their service has been amazing. When we transitioned our office phones and internett to BC, the team was quick to answer queries and gave regular updates during the process. The support team is always quick to respond to queries and provide updates to our phone system and provide solutions to any issues we have.
When It’s Time to Move On From Avaya
For many businesses, the tipping point comes when maintenance costs increase and system limitations start affecting customer experience. Older Avaya platforms can struggle to scale, integrate with modern tools, or support office relocations without significant reconfiguration.
At this stage, businesses often transition to a cloud PBX solution, removing the need for on-site hardware altogether. This allows staff to take calls from desk phones, mobiles, or softphones while keeping existing business numbers.
Others choose to consolidate calling and collaboration by moving to Microsoft Teams Calling, particularly if Teams is already used internally. This approach simplifies infrastructure while improving flexibility.

Avaya Phone System Relocations and Migrations
Office relocations are one of the most common times Avaya systems fail. Changes to IP addressing, cabling, and carrier services can cause systems to go offline without warning. Reinstalling an aging PBX at a new site often creates more problems than it solves.
BroadConnect helps businesses plan smooth Avaya migrations during relocations, ensuring phone numbers are retained, call flows are rebuilt correctly, and downtime is minimised. In many cases, relocation becomes the ideal moment to move to a modern business phone system that is location-independent.
How BroadConnect Supports Avaya Systems
With decades of experience supporting legacy and modern telephony platforms, BroadConnect provides honest guidance based on what’s best for your business. We can stabilise existing Avaya systems where possible, or design a clean migration path when the system has reached end-of-life.
Our Australian-based team handles troubleshooting, carrier alignment, number porting, and full system transitions — all without disruption to your customers.
