This is a wild guess, but let me throw it out there.  Take a look at 
the User-Agent: header from a Cisco ATA-186 or maybe from one of the 
Packet8 devices.  Then, go into chan_sip.c and alter the User-Agent: 
setting from "Asterisk PBX" to one of those values.  See if your 
dialing works.

Other providers have been known to implement this type of 
"User-Agent:" filter to (crudely) try to disallow certain types of 
equipment not on their "authorized" lists from accessing their 
systems.  I don't know if that's what happened with Packet8, but it's 
worth a shot, and will probably tell you more than calling their help 
desk.
