End of support for OpenScape Business V2 - what companies need to know now

Many companies in Austria continue to rely on OpenScape Business V2 as a proven telephony solution in their day-to-day operations. But this era will soon come to an end:
Official support for all OpenScape Business V2 mainboards will expire on 31 December 2026.

OpenScape Business V2: End of support on 31 December 2026

The end of support for OpenScape Business V2 has been officially set for 31 December 2026. From this date, the manufacturer will discontinue all software updates, security updates, technical support and feature enhancements.

In concrete terms, this means for companies

No security updates → increased cyber risk
No bug fixes → Growing instability
No new features → Increasing incompatibilities
No official support → Failure risk and loss of SLA

Which systems are affected by the end of support for OpenScape Business V2?

The end of support affects all solutions based on V2 mainboard technology, including

Unify / Atos / Mitel OpenScape Business V2
Telekom Octopus FX V2
OEM variants of the same platform

Even if individual systems are branded or customised differently, the underlying technology is based on the same platform - and is therefore covered by the end of support for OpenScape Business V2.

Why the end of support for OpenScape Business V2 is critical for companies

Although operation beyond 2026 is technically possible, it is associated with considerable risks:

SIP providers increasingly require newer security standards
Remote services (e.g. RSP) no longer work reliably without updates
Integrations such as Microsoft Teams will be limited or unstable
Cybersecurity risks increase massively without security patches

For companies, this can quickly lead to system failures, security incidents or unplanned additional costs.

What should companies do now?

With the end of support for OpenScape Business V2 approaching, early planning is essential. Many integration partners warn against starting the changeover too late, as there may be bottlenecks in hardware, consulting and installation capacity shortly before the deadline.

Conclusion: Use the end of support for OpenScape Business V2 as an opportunity. OpenScape Business V2 will reach the end of its support on 31 December 2026 and companies should consider a migration strategy now at the latest. The good news is that migrating to the modern OpenScape Business V3 generation is straightforward and cost-effective in many cases. Companies that plan now not only secure their communications infrastructure, but also create the basis for greater security, flexibility and future viability.
