On some phones running snom firmware 7.3.7 and newer, the phone can become unresponsive and even reboot, when using Flexor Call Control features e.g. putting a call on hold (from the Flexor Call summary window). This issue has been resolved by firmware 7.3.30.
Setting the snom phone with an HTTP Server User name and Password, can result in the phone becoming unstable, if the user ends a call or puts a call on hold, using the Flexor Call control features. Current advise from snom regarding this, is to remove the HTTP Server User name and password.
