C65/C70N/C351N Troubleshooting: Adjust volume or mute causes the call to get lost

Question

When I adjust the volume or mute the headset the call is then lost.

Answer

Certain DECT phones including the BT Calypso 1100 although are stated as GAP have been implemented in such a way that not all functions of the C65/C70/C351N work correctly. Refer to the compatibility database for up to date information.
