Fuuuuuu....That almost sounds like someone found a way to contact Level3 via 
your IP without ever touching sipX (this assumes Level3 is doing IP 
authentication instead of user/pass authentication).

just got a bill for 95,000 mins from level3.
calls we did not make, calls that do not show up in cdr.

(I see an INBOUND call from one of the numbers)

did shows our main did, (which never makes calls. there isn't any lines here 
that use that did)
calls originate after hours.

the one INBOUND that matches one of the numbers might be someone calling back 
to see who called them.

calls are 330******* numbers, all in a row, one line at a time, one number at a 
time.

can sipx make calls that are NOT recorded in CDR?
