[Devel] pinging UA not behind NAT

[Dan Pascu]

I remember this issue was fixed in cvs head, but I now observe the same 
behavior with openser-1.0.1

I have a phone which is not behind NAT and in the location table the flags 
field is 0 (i.e. no nat flag was set for it). Still I see the 4 byte 
pings sent to this phone by the nathelper module (I loaded nathelper to 
be able to send OPTION pings, but apparently with flags=0 in the database 
nathelper sends dummy pings even though it shouldn't send any, nor 
OPTIONS nor dummy)

The pinging from mediaproxy is disabled completely, so I assume this is 
either from nathelper, or it's the same problem as it was in cvs head.
