What is this super high fidelity phone connections! I would think they could get by with a lot less then that even with overhead. Given a 3K voice channel you should be able to sample at 12-16K, Add overhead and control.. so we double that... 32K ... what the heck is the rest? I think verizon breaks a T1 down into 23 voice channels / 1 control, each 48K. That always seemed like a waste of BW to me. I must be too tired to follow what you're saying. I'll just say that I'm happy with Vonage running over Comcast with a UPS just in case. Vonage comes out to around $28 per month including taxes. I don't have a wired phone anymore, although the wife does have a cell phone. ___________________________________________________________________________ Philadelphia Linux Users Group -- http://www.phillylinux.org Announcements - http://lists.phillylinux.org/mailman/listinfo/plug-announce General Discussion -- http://lists.phillylinux.org/mailman/listinfo/plug
