Refurbished Siemens Phones and HiPath Phone Systems
Siemens is a German engineering group whose former enterprise communications business made the HiPath phone systems and the optiset, optiPoint and OpenStage desk phones that run on them. That business was renamed Unify in 2013, so later models carry the Unify name.
This page holds Siemens-era equipment, most of it refurbished: HiPath 3000 systems such as the HiPath 3550 and 3800, system cards and voicemail, optiPoint and OpenStage handsets, key modules and Gigaset DECT phones. For models sold under the Unify and OpenScape names, see Unify. Browse Siemens IP phones and Siemens digital phones by type.

How to choose Siemens phones and parts
HFA, SIP or T version
OpenStage phones come in versions. HFA models are IP phones for HiPath and OpenScape Business, SIP models suit SIP platforms, and T models are digital phones for a HiPath extension port. The version is part of the model name, as in OpenStage 40 T.
optiPoint and optiset generations
optiset E and optiPoint 500 phones are digital handsets for HiPath and older Hicom systems. The optiPoint 410 and 420 are IP models. Names such as Entry, Economy, Basic, Standard and Advance mark the display and number of keys.
Match the HiPath model
Check the model on your system, such as HiPath 3300, 3500, 3550 or 3800. Card ranges differ between models, so read the name on the card you replace before you order Siemens system cards. Voicemail cards and modules are model-specific too.
Key modules and adapters
Busy desks add an optiPoint or OpenStage key module for extra programmable keys. Many optiPoint 500 phones also take adapters, such as the optiPoint analog adapter, to connect another device. Match each add-on to your phone generation.
Gigaset and system DECT
Gigaset handsets such as the R650H PRO register to Gigaset bases, and the CX253 ISDN connects to an ISDN line. System DECT handsets, such as the OpenScape S5, use HiPath Cordless base stations such as the BS4. See Gigaset for bases and the current range.

Questions
How much does a Siemens phone cost?
The cost depends on the model, its version (HFA, SIP or T), the condition grade and how many you need. Send the models and quantities through a quote request for a current figure. For a larger order, include your HiPath model so we can check the match.
Can I use a Siemens phone on a landline?
Only some models. optiPoint and OpenStage desk phones need a Siemens or Unify system. For a direct line, use an analogue phone such as the Euroset 5005, or a Gigaset DECT phone with a base that suits your line, such as the CX253 ISDN for an ISDN line.
Do you sell Siemens mobile phones?
No, this range is business equipment only: Siemens desk phones, DECT handsets, HiPath phone systems and system parts for offices that run a Siemens system or need spare parts for one.
Which Siemens phone systems are on this page?
Mostly HiPath 3000 systems, such as the HiPath 3300, 3500, 3550 and 3800, with their cards and voicemail. The HiPath 3000 range was followed by OpenScape Business under the Unify name. If you are replacing your system, we also buy used phones and systems.
Does Siemens still make business phones?
No. The Siemens enterprise phone business became Unify in 2013, and Unify has been part of Mitel since 2023. The former Siemens home and office DECT phones continue under the Gigaset brand. Refurbished Siemens-era phones keep many existing systems running.
