Summary:                    Cisco 7940 Fails to Register in 1.6.x after upgrade
Description: 
Having the same network config, 7940, NAT, Asterisk v1.4, the phone
registers OK.

After upgrading to 1.6.0.3 or 1.6.1-beta4, Asterisk doesn't reply to the
REGISTER messages, although the received messages from the phone are
displayed on the console, no replies are seen to be sent - not even replies
denying the registration.

Yes, but I updated the sipfriends table with all the new fields, directly
applied the sql script, and it didn't do it. 

Then, I entered a friend in the flat file, disabled sippeers and sipusers
in extconfig.conf and still only see the received messages, no outgoing
messages to the phone...


Flat file entry:

[7940]
type=friend
username=7940
secret=1234
host=dynamic
context=publicdialplanobd
accountcode=comtelnetworks
nat=yes
callerid=<7940>
disallow=all
allow=ulaw
allow=g729



Received REGISTER message:

<--- SIP read from UDP://71.x.x.x:5060 --->

Again, no response to the phone...

Can it be something regarding NAT, STUN that makes Asterisk ignore
incoming messages from certain types of connections?

When registering from another box within the same public network it works
alright. I don't have an IP Phone with a public address to test right
now...

In 1.4.22 registrations work perfectly. I'm also trying phsultan's trunk
version, where gtalk got to work fine to send and receive messages, but I
find this problem also with registrations...
