asterisk users - Oct 2009 - sip fullcontact and port values

Hi

We're using asterisk 1.4.17 with RealTime so our port and fullcontact 
values in out DB get updated dynamically.

We use snom handsets and always set the network identity (port) in each 
phone to something in the 10000 range, so that each phone in a single 
location has a different port.

When we look in the DB the location always has the port we set but the 
port value is often something else? What do these 2 values actually do 
and where is the port value being generated?

Thanks in advance
