Siemens HiPath 3550 / HiPath 3000 / DX Replacement
**Status: End of Support since April 2017.**
If your business is running a HiPath 3550, HiPath 3000, HiPath 3800 or DX/Realitis switchboard, Siemens and Unify stopped supporting these systems years ago. For a system this central to your daily operations, that’s a bigger risk than it might feel like today — most businesses only notice when something breaks.
The risk of staying on HiPath 3000/3550/3800
– No software patches — any vulnerability found in the platform stays unpatched indefinitely- Parts scarcity — line cards, extension cards and power supplies are refurbished-only, and stock is shrinking
– No vendor escalation path — if something goes wrong that your installer can’t fix locally, Unify no longer provides backline support
– Growing incompatibility — as ISDN is phased out by network providers, HiPath 3000/3550 systems built around it become harder to keep operational at all
– Handsets Optipoint and Openstage phones are all end of life and only refurbished available
The replacement: OpenScape Business X5 / X8
The direct successor to the HiPath 3000/3550 range is the Unify OpenScape Business X5 and X8], sized for the same 30–500 user range you’re likely running today.
– Supports both traditional ISDN lines and VoIP/SIP trunks, so you’re not forced to switch everything over on day one
– Digital and IP handsets from the OpenScape range give staff caller display, presence and mobile-app extensions
– Actively supported, with current spare parts and firmware updates
– Scales from 30 users up to several hundred without a platform change
Two replacement paths, depending on budget and complexity
Systems this size (30–500 users) often have years of custom configuration — hunt groups, call centre queues, ProCenter Agile setups.
That complexity is exactly what determines which path makes sense for you.
Option A: OpenScape Business X5 / X8 (full replacement)
The direct successor to the HiPath 3000/3550 range, sized for the same user count you’re likely running today.
– Supports both ISDN and VoIP/SIP trunks, so you can transition gradually
– Digital and IP handsets with caller display, presence, mobile-app extensions
– Actively supported, current spare parts and firmware
– Scales from 30 to several hundred users without a platform change
– Best fit if you rely on call centre features, complex routing, or can’t afford any drop in call-handling capability
Option B: Lower-cost hosted/cloud VoIP (budget-driven)
For businesses where the HiPath 3000/3550 is mostly being used for straightforward line and extension management — without heavy reliance
on ProCenter Agile-style call centre features — a hosted VoIP platform can replace it at a significantly lower cost, with no on-site PABX hardware to maintain or eventually replace again.
This is the right conversation to have if the OpenScape X5/X8 quote is more than the business wants to commit to right now, or if you’re open to simplifying your call-handling setup as part of the move.
Compare the budget VoIP alternative in detail
What migration looks like either way
1. On-site or remote audit** of your current trunk configuration, hunt groups, call centre setup, and extension mapping — this is what tells us honestly whether the budget option will actually cover your needs.
2. Two proposals — a full OpenScape quote and a budget VoIP quote, so the decision is yours to make with real numbers in front of you.
3. Phased migration plan for larger sites, staged by department or line group rather than the whole business at once.
4. Post-migration support, regardless of which path you choose.
Get your migration assessed — both options costed
Every HiPath 3000/3550 install is configured differently after years of changes. Rather than guess at a price, we’ll walk through your actual setup and give you a straight comparison of both paths.

Attendant Consoles:
optiPoint Attendant – An optiPoint system telephone can be used as an attendant console. This can be organized as an information, intercept, or night service station.
The attendant console can be accessed internally via a second directory number.
If the number of users on hold reaches a preset level, calls will be forwarded to a specified destination. This will also take place when the length of time a call is queued exceeds a specified limit.
optiClient Attendant – This software package simulates an enhanced attendant console on a PC’s screen. All features can be activated and executed via the PC keyboard and mouse.
The PC Attendant can be connected via V.24, USB or via IP.
optiPoint BLF – The busy lamp field (BLF) is an additional module principally for optiPoint Attendant. BLF has over 90 freely programmable function keys which show a station’s call status via LED (free, busy, called).
Braille console – (blind operator console) Optical displays are translated into Braille by an add-on device connected to the PC. This enables visually impaired employees to perform all call processing tasks. (Not available in all countries.)
Executive/Secretary Features
* Camp-on at an executive’s phone by the secretary’s phone
* Secretarial function transfer
* Call transfer to the secretary’s phone
* DSS keys for executive/secretary
* Conference corner telephone with parallel call signaling to the executive’s phone

PBX Phone System Administration:
System administration by the customer can be carried out either using the telephone or with HiPath 3000/5000 Manager C(additional information available in the HiPath 3000/5000 Manager C datasheet).
HiPath 3000/5000 Manager C is a customer tool that runs under Microsoft® Windows and is connected to the system via a V.24, S0 or TCP/IP-based LAN interface.
The feature Assistant TC allows customers to perform administration tasks on any system telephone with a display. The optiPoint 600 telephone is recommended, as this has an optional alphanumeric keypad (e.g for entering station names, etc.).
Relocate/Mobility (IP Telephones) – These features enable several users to share a workstation or to work as teleworkers from home keeping their extension numbers. The telephone retrieves personal settings when the user logs on. Extension numbers, station features and key labeling* remain unchanged (*for optiPoint 420 with self-labeling keys).

VoIP: HG 1500 converts voice signals into IP data packets, which can then transmitted be via the data network. Application interfaces: HG 1500 provides the foundation for the web-based use of third-party applications. No external routers or additional servers are required for LAN PCs because the router functionality, firewall functions, and security options are already integrated components of HG 1500.
Call Charge Management – A variety of PC programs are available for recording and assigning incoming and outgoing call charges, permitting evaluation by extension, trunk, department etc. The call charge data can be transmitted directly to a central server via the LAN interface.
Networking
IP Networking – With HiPath 3000 it is possible to network multiple locations (nodes) via IP -based data lines.
HiPath 3000/4000/5000 networking is based on the CorNet IP protocol.
HiPath 4000 Small Remote Site – HiPath 3000 can be employed as a Surviable Media Gateway for HiPath 4000 in small branches with up to 15 subscribers.
Virtual Network – A virtual network of HiPath systems via digital dial-up lines is economically advisable in situations where permanent connections are not viable due to low traffic levels or where the full range of services offered by a permanent connection is not required.
Least Cost Routing
HiPath 3000 uses this function to automatically control the path used for an outgoing call. Connections can be routed via various carriers or a private network. The routing tables are used to find the most favorable connection path for external calls.
Since individual network providers often offer different tariffs for certain connections and conditions, Least Cost Routing enables the most economical connection for each outgoing telephone call to be selected automatically depending on the time of day and route.
