I connect the Jabra Pro USB Headset to my SNOM D315 with the latest firmware (headset and phone). If i then get a call then i can answer it with the headset. If i get then een second call then i see in the manual that if i hold that button for 2 seconds that i get the second call. But if i try that nothing happens. I looked at all the settings in my phone and on the headset. Do you guys have a suggestion.
i've checked it with our QA department and unfortunately this function is not supported with our phones.
