I see a some VoIP files here: http://www.usamtb.com/thibor/files/ Can these help my VoIP setup w/ 15c? If so how do I install them or are they part of the 15c-Grcore6 upgrade that I already did? Already have mac of Sunrocket Gizmo set to Highest and Ports 5060 set to highest also. I have it on Auto in QoS an sometimes get garbled voice coming in? Thanks... ps,,,love this Thibor 15c on my SL for the last few months! Never a reboot needed!
