These were captured running my "v2" patch, since the phone cannot
register without it:

http://lkml.org/lkml/2010/11/14/181

goodreg.pcap - good registration
goodcall.pcap - call initiation + termination

This is all that happens in the absence of the "Cisco patch":

badreg.pcap - bad registration

Phone's LAN IP is 192.168.0.28
Public IP (as seen by the SIP proxy) is 111.222.33.222
SIP proxy is sip.iptel.org = 213.192.59.75
