Siemens OpenScape Migration
OpenScape Business is where every discontinued HiPath system ends up —it’s the current, actively supported Unify platform, and the direct replacement path for HiPath 1120, 1150, 3000, 3550, 3800 and 4000 systems.
This page is for anyone who wants full feature parity with their existing HiPath setup and isn’t primarily driven by finding the cheapest option.
If budget is the main concern, you may want to compare this against our lower-cost VoIP alternative first — we’ll cost both for you either way.
What changes, and what doesn’t
What stays the same:
– Your extension numbers
– Your existing call-routing logic (hunt groups, night service, call forwarding rules)
– Your handsets, where they’re compatible with OpenScape (many Optipoint and Openstage phones carry across)
– Your direct dial numbers and trunk configuration
What improves:
– VoIP/SIP trunking alongside or instead of ISDN, typically reducing call costs
– Mobile and home-office extensions — staff can take their desk extension with them
– A currently-supported platform, meaning firmware updates and available spare parts going forward
– Presence, voicemail-to-email and softphone options that legacy HiPath hardware doesn’t support
Which OpenScape system replaces yours
| Legacy system | OpenScape replacement | Typical size |
| HiPath 1120 / 1130 / 1150 | OpenScape Business X3 | Up to 30 users |
| HiPath 3000 / 3550 / 3800 / DX | OpenScape Business X5 / X8 | 30–500 users |
| HiPath 4000 | OpenScape Business / OpenScape Voice | 500+ users |
Is OpenScape worth the extra cost over a budget alternative?
Usually, yes, if any of these apply to you:
– You run a call centre or use ProCenter Agile-style queuing
– You have more than 30 extensions with complex routing rules
– You need guaranteed feature parity with zero retraining
– You want on-site hardware and a single local support relationship
If none of those apply — say, a small office mainly making and receiving straightforward calls — the budget VoIP alternative may cover what you need at a lower price. We’ll tell you honestly which camp you’re in during the free assessment.
The migration process
1. Discovery call or site visit — we map your current lines, extensions, and any add-ons (call recording, door phones, call centre queues) so the quote reflects your actual setup, not a generic package.
2. Migration plan — sized to your business, with a fixed price and a proposed cutover date, usually outside business hours.
3. Staging and testing — the new OpenScape system is configured and tested against your call-flow requirements before go-live.
4. Cutover — extensions, trunk lines and features move across in a single scheduled window.
5. Handover and support — your team gets a short walkthrough of anything new (mobile app, voicemail-to-email), and the system is covered by ongoing Unify support from day one.
