SIP stations for PBX servers and serverless communication

With a passion for secure communication

SIP stations by Commend are designed to always connect you to the right contact person – whether at the car park gate or entrance door, at the bus stop or information/emergency call terminal.

Reliably and in perfect speech quality.

Compatible with SIP PBX Server

Seemless integration into VirtuoSIS

The Software Intercom Server supports SIP stations as well as 3rd-party SIP phones. This allows for adding features such as group calls, audio recording, interfacing with external systems (e. g., visualisation), and many more.

Pure Serverless Communication

SIP stations and SIP capable telephones interface seamlessly into an intelligent communication network without the need for a server.

Voice messages

Always there for you
Automated voice messages for welcoming visitors or reassuring emergency callers Pressing the call button at an entrance or emergency call station triggers the playback of a customised voice message, reassuring the caller that someone will be available shortly to assist them.
Input/Outputs
Relays and attendant contacts enable powerful control functions
More than just communication Stations come with the ability to remote-control relays.
- Doors, shutters, gates and barriers open effortlessly at the touch of a button (desktop or mobile telephone) or by remote control via a third-party system (http request)
- Easy control of signal lamps and other subsections
Attendant contacts for additional indication of operating states such as Error, Ringing, Active Call, etc. (e. g., automatic activation of flashing light signal to indicate incoming calls).
Redundancy
Always at your service, thanks to redundancy
Functionality for more security
Stations can be logged in at up to three servers simultaneously
Calls are transmitted via the active server
In case none of the servers can be reached, the system can try to establish a serverless connection if necessary – e.g., by calling all stations on the network
Low costs
Electricity costs as low as €2.60 a year
A nice contribution to the environment When it comes to low power consumption, Commend’s SIP stations are second to none.
Approx. 1.5 Watts in standby mode, and only 2 Watts in call mode, depending on the volume level
Power can be supplied via PoE or an external power adapter
Wide range of functions
Wide range of functions
Telephone directory and web call
Connection ports for external amplifier and loudspeakers
Connection ports for add-on modules (loudspeaker, direct dialling buttons, handset)
SNMP for station monitoring
http support for network-based control of stations
Location identification

Where is the call coming from?
Location identification messages provide information for users at the control desk or query point An optional location identification message (e. g., “Emergency Call Station at Subway Station West Park”) can be defined for each station individually. The identification message is played back automatically when the operator at the control desk or query point takes the call. This way, the operator knows immediately where the call is coming from without having to ask. This is particularly important if there is no visualisation system installed at the Control Desk or Query Point, or if the call is relayed to a mobile phone.
LS-MIC Monitoring

Loudspeaker-Microphone Monitoring
Functionality that enhances security This causes the SIP Station to emit an unnoticeable audio test signal through the loudspeaker, which is picked up and analysed by the microphone. If the test signal does not arrive in the required quality (e. g., due to chewing gum blocking the microphone), the station will notify the receiving station accordingly. This ensures constant availability without the need for regular manual inspections, which goes a long way towards saving costs. More about Loudspeaker-Microphone Monitoring
Configuration made easy

Configuration made easy
The stations are specifically designed for easy, convenient configuration over the special Web Interface. A few clicks is all it takes to perform an update and even set up complex action sequences. For large-scale installations, the provisioning function helps to deploy configuration settings automatically and conveniently to thousands of connected stations at once.
