SIP strangeness on T-W cable ?

[johnl at iecc.com (John Levine)]

Today I am unable to connect to my usual SIP servers from my T-W cable
account.  I've tried two Sipura terminal adapters and the softphone in
Jitsi, and I can't connect to either callcentric.com or
voipdiscount.com, and the network connection is otherwise looking
normal.  The SIP providers are up, if I call my callcentric number
from the other line it goes to voicemail as you'd expect.

Anyone else seeing SIP wierdness on T-W today?

R's,
John
