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 From rising maintenance costs and security breaches to lost productivity and poor customer experience – sticking with outdated systems like Avaya and Mitel can cost your business dearly.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 Outdated systems such as Avaya and Mitel increasingly require manual interventions and struggle with modern integrations, resulting in higher operational costs.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What security risks do outdated phone systems pose?
Outdated phone systems have serious security vulnerabilities due to missing security updates, weak encryption and outdated authentication methods.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 With an outdated system, you run the risk of fines and reputational damage in the event of a data breach.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.
We help organizations move from legacy systems to modern, future-proof communication solutions. With custom solutions built from proven standard building blocks, without the high cost of traditional development work. Our platform integrates seamlessly with Microsoft Teams and other enterprise systems, while ensuring full compliance with ISO 27001, ISO 9001 and ISO 26000 certifications.
Frequently Asked Questions
How long does the transition from a legacy telephony system to a modern solution take?
The transition takes an average of 4-8 weeks, depending on the complexity of your current setup and the number of users. A phased migration ensures that your business operations are not interrupted. We typically schedule the transition on weekends or outside business hours to minimize downtime.
What happens to our existing phone numbers during a system replacement?
All your existing phone numbers are retained during the transition. We arrange number portability with your current provider and ensure that no calls are lost. The process is completely transparent to your customers - they only notice improved quality and functionality.
How much can I save by switching from my legacy system?
Organizations save on average 30-50% on their total telephony costs within the first year. This comes from lower maintenance costs, eliminated licensing costs for legacy software, and more efficient communications. The savings become greater the older your legacy system is and requires more maintenance.
Can employees continue to use their current phones?
In most cases, existing IP phones can be reused, provided they are SIP compatible. For very old phones, we recommend replacement with modern devices that integrate better with new features such as video calling and Teams integration. We assess your current hardware during intake and advise on reuse.
What if our employees have trouble transitioning to a new system?
We provide comprehensive training and support during the transition. Modern systems are more intuitive than legacy solutions, so most users experience it as an improvement. We host hands-on training sessions, create instructional videos and provide additional support during the first few months to ensure a smooth transition.
What about security during and after the migration?
Security is central to our migration process. We implement end-to-end encryption, multi-factor authentication and continuous monitoring from day one. You are immediately more secure than with your legacy system, and we provide automatic security updates and compliance with AVG and other regulations.
What happens if the new system goes down or has problems?
Modern cloud-based systems have 99.9% uptime and built-in redundancy. If problems do occur, we provide 24/7 monitoring and support. We have automatic failover mechanisms and can detect and resolve problems within minutes, much faster than was possible with legacy systems.
