It looks like this started happening in parts of Mexico about two weeks ago. In Mazatlan, Vonage, Skype, Mediaring, etc no longer function. Tests to www.testyourvoip.com fail badly on the upload(well over 50% loss). Calls to tech support at Telmex Prodigy DSL have not been useful. Some users have even reported that tech support admits they're degrading voip upload traffic. Oddly, Telmex Prodigy DSL does not offer their own voip option at this time. Cable internet is still working fine....for now.
