You're not going to get a telnet connection on port 5060, since that's tcp and 
sip uses UDP.

Use tcpdump/wireshark on your office pbx to see if the packets are getting to 
you. If not, then there's something wrong inbetween.

A firewall misconfig, perhaps. Or the unthinkable:  your home ISP has started 
filtering 5060.

I have a home asterisk box which connects to the office asterisk, so I can just 
dial extensions.

This used to work just fine. I'm using 10.0-rc1 on the home box, 1.8.7.0 on the 
office. But it doesn't work now:

[Nov 14 18:38:19] NOTICE[21563]: chan_sip.c:13161 sip_reg_timeout:    -- Registration 
for 'sip@<officePBX>' timed out, trying again (Attempt #86)

I first thought it was some fall out of the new upgrade to 10.0-rc1, but now 
I'm not sure.

Even with verbose at 6 I don't see anything on the office console about the 
attempted registration.

And on the office:

lsof -i:5060
COMMAND   PID     USER   FD   TYPE DEVICE SIZE/OFF NODE NAME
asterisk 2045 asterisk   15u  IPv4  23030      0t0  UDP *:sip

but:

telnet localhost 5060
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused

iptables is set to allow 5060 udp and tcp. And I've flushed iptables, but still 
no luck.

I can ssh into the office box from the home box. The office box is directly 
connected, the home nat'ed.

Any help really appreciated.

Unthinkable!! Used wireshark: I can see the REGISTER packets going out from the home router, but nothing from home:5060 shows up at the office.

Bummer. Now I get to think about how to set up special ports between home and office. A great evening activity.
