Hi, my client has Snom 715 devices connected via STUN and they have a Jabra Evolve 65 wireless headset. The headset is connected via the usb-dongle of the Jabra directly on the Snom phone AND via bluetooth on the mac. When they call via the Mac Client App the headset is not working. As soon as they remove the usb-dongle from the SNOM, the headset will work fine with the mac app. Is this a known issue or ... ??
