How Many Simultaneous VOIP Voice Calls Can 1 Comcast Internet Connection Support?

Last Modified: 2013-11-12
If I have a Comcast internet connection at 6mbps down and 1.5mbps up, how many simultaneous VOIP calls will that support?  There would be a Digium TE122B card involved which supposedly supports 24 and 32 channel connections.  My assumption is, 1 voice call per channel but how many channels are in a Comcast connection at 6mbps down and 1.5mbps up?  Thanks!
