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.

How about using multiple IP tables entries to redirect several ports
down to 5060. Dunno if it would work, just a wild-hair guess. I should
test it later.
It won't, because SIP signaling requires that the UAs include their own
addresses and ports in the signaling, which requires that they know what
they are :-) There are some tricks that can be used to get around it,
but they aren't trivial and they require that the mapping be done
bidirectionally by whatever is doing the SNAT/DNAT stuff.
