Legacy telephony systems carry increasing risks as they age. From rising maintenance costs and security breaches to lost productivity and poor customer experience – sticking with outdated systems like Avaya and Mitel can cost your business dearly. The cost of deferring is getting higher every month, while modern alternatives are becoming more accessible.
Why are legacy telephony systems becoming increasingly expensive to maintain?
Legacy telephony systems are becoming exponentially more expensive due to scarcity of specialists, rising parts costs and mounting technical debt. Outdated systems such as Avaya and Mitel increasingly require manual interventions and struggle with modern integrations, resulting in higher operational costs.
The specialists still familiar with these old systems are becoming scarce and therefore expensive. Many of them have retired or switched to more modern technologies. This means that you have to pay more and more for the same maintenance.
Parts for legacy systems are often no longer in production, leaving you dependent on expensive refurbished components or costly custom solutions. Moreover, the problems pile up – every month you delay, the technical debt grows.
Integration with modern systems is also becoming increasingly problematic. You often need custom links that require a lot of maintenance. This creates a vicious cycle of rising costs and declining functionality.
What security risks do outdated phone systems pose?
Outdated phone systems have serious security vulnerabilities due to missing security updates, weak encryption and outdated authentication methods. These vulnerabilities make corporate data and customer calls accessible to cybercriminals, which can lead to data breaches and compliance issues.
Legacy systems often no longer receive security updates from the manufacturer. Known vulnerabilities thus remain, while hackers actively exploit them. Your phone traffic can be tapped or even taken over.
The encryption standards of old systems are obsolete. What was secure ten years ago is now relatively easy to crack. Customer conversations with sensitive information are at risk of interception.
Compliance is also becoming an issue. Regulations such as the AVG require adequate technical security measures. With an outdated system, you run the risk of fines and reputational damage in the event of a data breach.
How do old telephony systems limit employee productivity?
Old telephony systems limit productivity due to lack of mobile integration, missing modern features and poor user experience. Employees cannot work flexibly, miss important calls and waste time on cumbersome procedures that modern systems automate.
Hybrid working becomes nearly impossible with legacy telephony. Employees cannot switch seamlessly between the office and working from home. They miss calls or have to set up cumbersome workarounds that often don’t work well.
Modern features such as click-to-call, integrated voicemail and automatic call notes are missing. Employees waste time on manual tasks that could be automated.
The user experience is often frustrating. Complicated key combinations, unclear menus and slow systems create daily irritations. This leads to lower employee satisfaction and more customer service errors.
What are the implications for customer experience when using legacy telephony?
Legacy telephony degrades the customer experience through fragmented communication channels, longer wait times and lack of omnichannel capabilities. Customers have to tell their story over and over again and cannot switch seamlessly between phone, email and chat, leading to frustration and customer turnover.
The biggest problem is that customer information is scattered across different systems. A customer who first calls and then sends an email has to tell their story twice because the systems don’t talk to each other.
Modern customers expect to be able to choose how they contact them. They want to be able to start via WhatsApp, switch to a phone call and then receive an email – all within the same conversation. Legacy systems make this impossible.
AI-driven features such as smart routing, automated responses and predictive analytics are completely lacking. As a result, customers take longer to get to the right person and receive less personalized service.
When is it time to replace your legacy telephony system?
It’s time for replacement when maintenance costs rise, security updates are missing, employees complain about functionality, or customers become frustrated with poor accessibility. If your system is less than five years old or hybrid working is causing problems, an upgrade is urgent.
Look for concrete signs: are your telephony maintenance costs rising every year? Are employees having trouble working from home because the phone system is not cooperating? Do customers complain about poor accessibility or having to tell their story over and over again?
A modern omnichannel enterprise telephony solution offers not only long-term cost savings, but also immediate benefits such as better security, seamless mobile integration and AI-driven automation.
When choosing a new solution, it is important to choose a partner who can provide everything under one roof. That way you avoid complex integrations between different vendors and have a single point of contact for your entire communications infrastructure.

Frequently Asked Questions
Hoe lang duurt de overstap van een legacy telefoniesysteem naar een moderne oplossing?
De overstap duurt gemiddeld 4-8 weken, afhankelijk van de complexiteit van je huidige setup en het aantal gebruikers. Een gefaseerde migratie zorgt ervoor dat je bedrijfsvoering niet wordt onderbroken. Wij plannen de overstap meestal in het weekend of buiten kantooruren om downtime te minimaliseren.
Wat gebeurt er met onze bestaande telefoonnummers bij een systeemvervanging?
Al je bestaande telefoonnummers blijven behouden tijdens de overstap. We regelen de nummerportabiliteit met je huidige provider en zorgen ervoor dat er geen gesprekken verloren gaan. Het proces verloopt volledig transparant voor je klanten – zij merken alleen dat de kwaliteit en functionaliteit verbeteren.
Hoeveel kan ik besparen door over te stappen van mijn legacy systeem?
Organisaties besparen gemiddeld 30-50% op hun totale telefonie-kosten binnen het eerste jaar. Dit komt door lagere onderhoudskosten, wegvallende licentiekosten voor legacy software, en efficiëntere communicatie. De besparingen worden groter naarmate je legacy systeem ouder is en meer onderhoud nodig heeft.
Kunnen medewerkers hun huidige telefoons blijven gebruiken?
In de meeste gevallen kunnen bestaande IP-telefoons worden hergebruikt, mits ze SIP-compatibel zijn. Voor zeer oude toestellen adviseren we vervanging door moderne apparaten die beter integreren met nieuwe functies zoals videobellen en Teams-integratie. We beoordelen je huidige hardware tijdens de intake en adviseren over hergebruik.
Wat als onze medewerkers moeite hebben met de overgang naar een nieuw systeem?
We bieden uitgebreide training en ondersteuning tijdens de overstap. Moderne systemen zijn intuïtiever dan legacy oplossingen, dus de meeste gebruikers ervaren het als een verbetering. We organiseren hands-on trainingen, maken instructievideo’s en bieden de eerste maanden extra support om een soepele overgang te garanderen.
Hoe zit het met de beveiliging tijdens en na de migratie?
Beveiliging staat centraal in ons migratieproces. We implementeren end-to-end encryptie, multi-factor authenticatie en continue monitoring vanaf dag één. Je bent direct beter beveiligd dan met je legacy systeem, en we zorgen voor automatische security updates en compliance met AVG en andere regelgeving.
Wat gebeurt er als het nieuwe systeem uitvalt of problemen heeft?
Moderne cloud-gebaseerde systemen hebben een uptime van 99.9% en ingebouwde redundantie. Als er toch problemen zijn, bieden we 24/7 monitoring en support. We hebben automatische failover-mechanismen en kunnen binnen minuten problemen detecteren en oplossen, veel sneller dan bij legacy systemen mogelijk was.
