I put Skinny Broadband in at our local church with a 2talk phone line over the top, to replace an old Spark DSL/homeline plan that was costing them megabucks.  I had to run a VPN back to my house (on UFB) as I couldn't get 2talk to work over Skinny's CGNAT.

This is the smokeping for the VPN:

Jitter has got a lot worse in the last week or two and the VoIP has started cutting out quite a bit.

Can Skinny do anything about this?  We're out of our "first 30 days reception guarantee" by a month or two.  I'm already a bit annoyed because Geekzone posts suggested that 2talk worked over Skinny quite well at launch, but it clearly doesn't anymore.
