1. Requirements and Information
Using this snom IP telephone with your nfon telephone system merely requires a sound
broadband connection.
There can be delays with incoming and outgoing calls when using the snom 7xx series in
combination with a Plantronics DECT headset and a APU-71 EHS adapter.
The snom 715 is End of Life (EOL) since January 28, 2015.
To operate a snom D7 expansion module an update to firmware v 8.7.5.17 is necessary.
A total of three D7 modules can be daisy-chained. The chain is operated via USB cable.
From the second module onwards, an extra power supply unit is needed.
Please note: Telephones with the firmware 8.9.3.x should not be downgraded to a
firmware lower than 8.7.5.44, otherwise problems may occur if you try to upgrade again.
See the manufacturer's notice here.
2. Adding an extension
All telephones you receive are preconfigured and connected to the telephone system.
Find further information on how to install an extension in the administration portal
manual.
