In most cases, the failure of a meeting room's audio system and display is neither random nor inevitable. The fault doesn't start with the hardware — it starts with a lack of maintenance. The vast majority of meeting room systems degrade slowly, and with a proactive, professional approach, most faults can be identified and eliminated in advance. The specialists at GHT-SYS work every day to ensure that issues in meeting room systems can be avoided.
The short answer: because the system has been slowly deteriorating for weeks, possibly months, and what at first glance looks like a “random” outage is in fact the final step of a longer process.
Cisco's 2024 global hybrid workplace survey, conducted with 14,050 employees and 3,800 employers, found that 42 percent of European employers say inadequate audio and video endpoints are the main reason meeting rooms fail to effectively support productivity (Cisco Hybrid Work Study, March 2024). The primary draw of returning to the office is high-quality collaborative space, but in many places, the technology hasn't kept up with this expectation.
In Budapest, this is particularly tangible: by the end of 2025, the city's modern office market reached 4.46 million square meters (Budapest Office Market Forum, Q4 2025). A significant portion is occupied by SSCs, regional headquarters of multinational companies, and BPO centers, where daily operations depend heavily on meeting room technology. These organizations typically have 10–50 meeting rooms, drawn from multiple manufacturers, multiple generations, and running multiple AV platforms simultaneously.
In such an environment, restarting is not a solution — it's just a postponement.
This is the most common cause, and the one most often invisible to IT teams. A Teams Room update can change codec behavior or audio routing, or the control system may fail to recognize the new version. The same applies to Zoom Rooms and to hardware manufacturers such as Crestron and their firmware cycles.
According to Crestron's official Microsoft Teams Rooms documentation, the controller firmware downloaded by the Windows Update service can downgrade a higher version available on Crestron's website. This means that a simple Windows update can silently change the behavior of the meeting room because no one is tracking the firmware versions.
A recurring source of AV faults is outdated firmware or software, which can produce surprising behavior after platform updates. This can be prevented through regular, AV-specific update checks, which must be handled separately from IT's general software update process.

Behind intermittent, recurring symptoms there's most often a physical contact issue: a loosened HDMI connector, a slightly damaged cable, a mildly oxidized connection. This kind of fault can rarely be identified by restarting. It only comes to light through physical inspection.
Cable and connection problems usually don't appear overnight — they develop over weeks or even months, slowly worsening. One day the meeting room doesn't work, the next day it's fine, the day after that it fails again. Then IT closes the ticket because everything looks fine during inspection, but within three weeks the issue comes back.

The consolidation of the AV integrator industry in Europe accelerated in 2024–2025: the original installer gets acquired, shuts down, or simply doesn't prioritize maintaining previously installed systems. The client has no as-built drawings, no firmware list, and no admin access (AVNetwork, 2025).
When a fault occurs in such a system, diagnostics have to start from zero every time. There's no baseline, no comparison, no history. This isn't just a time cost: undocumented AV equipment runs on old firmware, and unknown vendor access points open up a cybersecurity gap (VIcom, February 2026).

IT typically doesn't want to be an AV specialist; facilities doesn't want to be a technology owner. This is the “no man's land” where everyday problems originate.
If the answer to “whose responsibility is the meeting room technology?” is IT and facilities pointing at each other, then the risk of important meetings being disrupted by technical issues is already present. The question isn't whether the system will hit a fault — only when. GHT-SYS fills exactly this role: as an AV specialist, it lifts off the shoulders of IT and facilities the responsibility that neither of them wants to take ownership of.
This is one of the most important insights this article aims to convey.
Restarting is only symptomatic treatment — it doesn't fix the root cause. If the same meeting room causes a problem for the third time in 30 days, a ticket closed with a restart isn't a solution; it's just sweeping the real problem under the rug.
The question an experienced AV specialist asks is not “is the system working right now?” but rather: when was it last inspected, not just repaired? What's the firmware version on the codec? Is there an equipment inventory? When was the cable and connector infrastructure last physically inspected?
According to a Ford AV industry analysis, the lifespan of videoconferencing systems, media processors, and networked AV systems is 3–5 years without maintenance, but with regular maintenance this can be significantly extended (Ford AV, December 2025). The maintenance fee is predictable; the real cost — when there's no maintenance contract — comes from unplanned repairs, emergency call-outs, IT labor hours, and the cost of executive time.
Proactive maintenance isn't a luxury — it's a cost-efficiency decision. According to a UK FM analysis by AM Planned Maintenance, planned maintenance is up to 30 percent cheaper than a reactive approach (AM Planned Maintenance, June 2025). The reason is simple: the cost of reactive repair, due to emergency call-out fees and the less reliable work performed under pressure, can be several times that of planned maintenance.

At one of our corporate clients, the accepted daily practice was to restart the boardroom control processor before every important meeting. No one ever questioned it, because “it's always worked that way.”
During our first inspection, we found that a buffer overflow in the original system programming was causing recurring system errors. The original installer hadn't dealt with the issue afterward, and the source code wasn't documented, so the program had to be rewritten from scratch.
The result: the boardroom worked reliably without restarts, and client satisfaction was maximized. All of this could have been avoided with properly executed and documented commissioning and/or appropriate SLA support.
If the previous installer is no longer available, there's no proper documentation, no equipment inventory, or the admin password is lost, the first diagnostic always comes with plenty of surprises.
This process may seem time-consuming at first glance, but the alternative is that with every fault, diagnostics have to start from scratch every single time.

What should you do now? 5 checkpoints
What is an SLA, and what does it mean for meeting room system maintenance?
An SLA (Service Level Agreement) is a contractual agreement that precisely defines what the client can expect from the maintenance partner: how quickly they respond to fault reports, how regularly they perform preventive checks, and what documentation obligations they have. For meeting room systems, an SLA isn't just about repair time — it also defines who is the responsible owner of the AV layer, and what happens when the system is quietly deteriorating, not just when it's already gone down. GHT-SYS's SLA-based maintenance includes regular firmware checks, physical cable and connector inspection, keeping the equipment inventory up to date, and analysis of recurring tickets.
Why is an SLA important for meeting room systems?
A meeting room SLA defines not only the response time but also the cadence of proactive maintenance, documentation obligations, and accountability. Without an SLA, the maintenance partner only learns about a problem when the client raises it. With an SLA, the system's condition is tracked through regular checks, and a portion of the faults can be caught before users ever notice them.
What's the difference between proactive and reactive maintenance?
Reactive maintenance responds to a fault. Proactive maintenance identifies risks in advance and doesn't wait for a fault to occur. Based on FM industry data, the proactive approach is up to 30 percent cheaper than the reactive one, because it doesn't include emergency call-out fees and doesn't cause unplanned downtime.
What does guaranteed response time mean from a service provider?
Guaranteed response time means that after a fault is reported, the service partner begins diagnostics within a defined timeframe. This is fixed and accountable. Without an SLA, response time depends on the current capacity of the service provider, not on the client's needs.
When is a meeting room audio system or display obsolete?
The lifespan of videoconferencing systems and networked AV systems without regular maintenance is 3–5 years; with proactive maintenance, this can be extended. The sign of obsolescence isn't just that the system goes down — it's also when it can no longer be integrated with the current platform version (Teams, Zoom), or when the manufacturer no longer supports firmware updates.
How do we take over an undocumented meeting room system?
In such cases, GHT-SYS starts with a physical system survey: what's in the rack, which device is running which firmware version, what the admin access details are, and what the current critical fault and risk picture looks like. After the first audit, the as-built documentation and the proposed SLA activity schedule are prepared. This is the foundation on which proactive maintenance is built.
If you can't say for certain what's in your meeting room rack, when firmware was last checked, or who tickets land with, an audit will give you a clear picture.
GHT-SYS carries out the system survey, shows you the current state and the real risks, and makes a concrete proposal for the first step.
