That first line is the sort of error I'd expect to see if your SIP

Ah, that's an interesting one. If I run the software on my laptop at
work (using 10.0.0.0/9 address space with NAT/PAT to the big wide world)
it works fine and registers. When I run the software with the same
dynamic configuration at home (using 192.168.128.0/21 address space with
NAT/PAT to the big wide world) it fails with this error.
I wonder whether the work firewall (a CISCO PIX) is doing in-packet
processing for SIP; I know I've had to disable the SIP alg on my home
Thanks for the thoughts.
