I am new to using this software PBX coming for using FreePBX so I hope I got this all right. First I am doing this setup in VMware workstation 10 which might be the issue since it does only list Vsphere 5.x. For some reason the YealinkT28's phones won't show up on the list. I have tried 2 phones and I have the required firmware. I even tried to config manually and I have no luck either. I am using Server 2012 R2 on VMWare Workstation 10 for now. Any help would be great.
