I have setup Zoiper5 on Windows 10. Freshphone acc registers fine. I can make outgoing calls from Zoiper no problem. In coming calls to my selected no 27872384081

There was no ring or any indication that the calls was coming in. I have tried two different incoming devices (on Zoiper) headset and conference phone Jabra)
