Yes, exactly: if you want to remove the phone, this also
removes the call. In TCP/IP, this isn't the case. Your
TCP connections will survive route changes, interface
removals, etc.

But not a change in IP address :-) TCP connections are
exactly like VCC's in this regard, the VCC here is defined
as saddr/sport/daddr/dport, and if any of these must change due
to an administrative act, it kills the "phone call" :-)
