No... but the problem turned out to be networking related as the ARP
replies weren't getting back to the phone. I plugged the phone into a

works now.
I must say that these phones are really nifty as SIP devices. Nice to be
able to press Messages and to hear "Comedian Mail" instead of the Cisco
voice :-)
