Intercom on OPUS


TDS12070 OPUS Intercom 00

If you have a VoIP SIP server, the OPUS touch screen can be connected to it, e.g. as a hands-free indoor device for video door entry. However, an intercom function is also possible. This then enables calls between different OPUS devices.

The different OPUS intercom options

• Call from an OPUS to another OPUS.
• Call from an OPUS to another type of internal VoIP SIP phone.
• Call from an OPUS to an external VoIP SIP phone or mobile phone (*).
• A group call from an OPUS to all other OPUS devices in the building.

The first person to pick up has the call and the other devices immediately stop calling.
Depending on the IP server capabilities, certain devices may be excluded where the call will not be heard (e.g. in the master bedroom).
• AUTOANSWER (*) group call from an OPUS to all other OPUS devices in the building.

(*) Provided your SIP server supports this functionality.

Some examples

''"Hello, dinner is ready"
'Hello Marie, your taxi has arrived'
Or in a corporate environment:
'Hello Wim, please contact Diek'
'Dear employees, our Indian colleagues are training with us today. They will also be present at lunch.'


TELETASK respects and guards the privacy of its customers. Eavesdropping with an OPUS device has therefore been made impossible. A call, to and from an OPUS device, can therefore last up to five minutes.
1. In case of an incoming call on the OPUS device (standard call):
This is only possible when there is a call (the ringing signal rings) and the call is answered by pressing the green handset on the touch screen. Only then can the user speak to the caller, until the user closes the call (red horn) or for a period of maximum of 5 minutes.
2. In case the user calls from an OPUS to another device (standard call):
Same as in the above case: If the call is not closed(from either side), the connection will be automatically disconnected when the maximum call time has passed.


• Define the OPUS devices in the configuration application of the SIP server, in order to provide them with a VoIP call ID.
• Create any desired Group call (VoIP call ID) numbers afterwards. Each such number contains all OPUS devices you want to be able to call in that group.
• Now enter the various OPUS devices in PROSOFT for standard VoIP operation as a IP camera. Go to the "Extra/IP cameras" menu and select "New" to do this. Do this for each OPUS device. Enter the name of the device (e.g. 'OPUS kitchen') and enter the VoIP Call-ID number (as defined in the SIP server settings above).
• Now also create one or more call group(s) in PROSOFT (same as above in the Extra / IP cameras menu). Each group call has its own VoIP call ID number and can be entered as a separate “IP camera”.
• Enter the name of this call group in 'camera name'.
e.g. 1 ’Call anywhere’.
e.g. 2 ‘Call kitchen and laundry room’
e.g. 3 "Transmit group message with AUTOANSWER" (e.g. to be able to say "come to dinner" or "time for school" through the loudspeaker of all or a limited number of OPUS devices.
e.g. 4 ‘Call discreetly’
• Enter the 'VoIP call ID' (the call n°. you want to use in the SIP server for this group).
e.g. '503' for group 1, '504' for group 2 and '505' for example 3, etc.
These numbers are dedicated and can be programmed in the SIP server used.

Note: Now confirm all settings to the DoIP central unit by sending the modified nbt file.
