[asterisk-users] Asterisk RealTime

[Nitesh Divecha]

Hello All,

I manage to configure Asterisk RealTime and now it loads the SIP 
users/peers from MySQL DB. The table I am using is of A2Billing DB 
"cc_sip_buddies".

Now the only problem I am facing is incoming calls are failing... The 
ATA which is assigned this DID number is behind NAT and according to 
Olle's explanations he said "*there's no support for NAT keep-alives 
(qualify=) or voicemail indications* for these peers." 
http://www.voip-info.org/wiki/view/Asterisk+RealTime

So does this mean that I can not have any ATA behind NAT with this kind 
of setup? Below is the error message.

NOTE: The same setup used to work when I was using flat file config.

Here is my "extconfig.conf": -
[settings]
sipusers => mysql,mya2billing,cc_sip_buddies
sippeers => mysql,mya2billing,cc_sip_buddies

Here is my "res_mysql.conf": -
[general]
dbhost = 127.0.0.1
dbname = mya2billing
dbuser = billinguser
dbpass = 000eFm500F9E36
dbport = 3306
dbsock = /tmp/mysql.sock

When I do "sip show peers" on the *CLI I can see my SIP user: -
hyperion*CLI> sip show peers
Name/username              Host            Dyn Nat ACL Port     Status

1 sip peers [1 online , 0 offline]

Error message while receiving the call: -

Any advice...
