asterisk users - Aug 2013 - External sip phones register with the servers IP...

We have just updated our office server to Asterisk 11.4.0 from 1.8.15 and
internally everything is working fine.  The problem we are having is that we
cannot use any external phone connected through the Internet.  This used to
work fine with 1.8 but since the upgrade whenever you register any phone from
an outside network the phone tries to register using the servers internal IP.  

I endo up having something like this:

Sending to 187.163.93.235:58545 (no NAT)
    -- Registered SIP '2003' at 192.168.2.50:58545
Reliably Transmitting (no NAT) to 192.168.2.50:58545:

I really cannot understand what is wrong, I have checked my sip.conf
configuration and it is the same as in past versions.  externaddr and localnet
are set to the proper values.  Any ideas?

Did you look at the CHANGES file?  There are new settings for NAT.  If you are
using the same settings as in 1.8, there is a posiblity that you will have
problems depending on what settings you have (which you did not include in this
message).

Also, I would recommend 11.5 since there was a one-way audio issue fixed related
to using the two new NAT settings.
