2N® SIP Audio Converter

Viel mehr als nur IP Paging

Der 2N® SIP Speaker hat einen neuen Namen: 2N® SIP Audio Converter

Der 2N® SIP Audio Converter ist eine IP Paging Anlage mit vielen nützlichen Funktionen, die an Arbeitsstätten, in Krankenhäusern, auf Ämtern und in sonstigen öffentlichen Räumen Anwendung finden. Sie können sie mit einem Lautsprecher als einfachen Rundfunk, eventuell auch mit einem Mikrofon also Zwei-Wege-Kommunikator verwenden. Die Verbindung von IP Technologie und SIP Protokoll bietet dabei die Möglichkeit, eine Meldung an alle Anlagen im Netz zu senden oder sich einzelne Zonen auszusuchen, gegebenenfalls die konkrete Anlage anzurufen. Mit dem angeschlossenen externen Mikrofon und dem Druckschalter kann die Endstation bis zu drei vorgewählte Nummern anrufen. Von diesen kann daraufhin ein externer Schaltermit einer beliebigen Funktion je nach Bedarf des jeweiligen Betriebs bedient werden.


Die ursprüngliche Technologie bat uns keine Möglichkeiten, die bestehende TK-Anlage und das alte Audiosystem zu verbinden. Die Klangqualität entsprach unseren Anforderungen nicht. Wir suchten deshalb nach einer Technologie, die uns eine Modernisierung und Verbindung mir dem IP-Welt ermöglichen würde.

2N® Network Scanner version 3.0.4

- 2N® Network Scanner can find devices without IP address
- 2N® Network Scanner can set basic network settings - DHCP on/off and set static IP address (same requirements as above) - units with this feature enabled and disabled are distinguished by color (grey ones can not be configured).
- 2N® Network Scanner can also locate devices in other network segments, if multicasts are routed between them
- Filtering in results
- Name change from 2N® Helios IP Network Scanner to 2N® Network Scanner as it is also able to find 2N® Access Unit and 2N® Indoor Touch

Location of devices without assigned IP address and network settings do work with 2N Helios IP intercoms, 2N® Access Unit and SIP IP audio with firmware version 2.15.0 and higher. This feature does not work with 2N® Indoor Touch version 1.6 and 2.0, however these devices are still located in the network with assigned IP address.

Door open on incoming call from predefined number - Automation Event.CallStateChanged has new parameter Number so that you can specify what shall be done according to who is calling or being called.
New event Event.CardHeld which is triggered if a user holds the RFID card at the reader for specified time - you can distinguish between swiping a card and holding the card, triggering two separate actions
Reason for failed registration added to event logging - so that monitoring system can react accordingly or provide proper information to maintenance crew

Multiple email addresses in email settings - semicolon is now accepted as separator, to match MS Outlook behaviour
Switch opened by time profile - this popular functionality is now available without need to use Automation. Licensing stays the same.
Multiple Access Keys - since a single intercom can belong to multiple groups of Indoor Touch, there is now an option to store multiple Access Keys

Support for Snom D765
Support for touchscreen display module for Verso
Support for My2N / Mobile Video
RFID card reader signalisation aligned between particular models. Parameter Card reader signalling is now consistent and even display equipped models do follow settings of visual signalisation.
Number of event log records stored in device increased from 500 to 10.000
Format of email message changed, plain text sent along with HTML so that Email to SMS on 2N® Voice Blue Next works nice for SMS access control notifications
