Thanks for the response. Home asterisk : 10.0.0  - Office: 1.8.8.0

So I thought I'd leave all the sip providers on udp, and move the 
home-office to tcp.

And registration just work Just Worked over the default tcp registry 
port - which I was surprised to learn was 5060, and not 5061.

So it appears cablevision only blocks udp 5060.
