Configuring the Leadtek BVA8052 for CIA

First, obtain the SIP credentials for your CIA account as described here.

Plug in the adapter (power, one of the Ethernet ports to your router and a phone into Line 1). Wait a few seconds, then pick up the phone and push the reset button briefly. The adapter will start playing a menu, hit 1 to listen to the IP address. Then enter that IP address in a browser.



Click SIP on the left menu, then SIP Config at the top



Enter the following settings:
- Server address: the SIP server (the value found under Proxy_1_ in the configuration file from CIA)
- Port: 5060
Under Line1:
- Phone number: this is the phone number, as found under User_ID_1_ in the configuration file
- CalledID Name: same as Phone Number
- User Name: same as Phone number
- Password: the SIP password from (found in the configuration file, under Password_1_)
- Dial Plan: copy/paste the following string
*xx|[2-9]11|[2-9]xxxxxxxxx|1[2-9]xxxxxxxxx|911|011xxxxx.T
 
Now click Save SIP Settings at the bottom, then go to the NAT Transversal menu:


 
Enter stun.xten.com under the Server Address and enable all the checkboxes except Attempt DNS discovery and Enable ICE like in the screenshot above, then click Save NAT Transversal Settings.

Next, click the CODECS link on the left menu.


Enable the G729 codec then click Save CODEC Configuration at the bottom.

Now reboot the adapter. Wait 1-2 minutes after which you should have dial tone.
 
To factory reset the adapter
- unplug the power.
- connect the telephone to PHONE 1 port and lift the handset off the telephone (off-hook)
- use a pin to push the RESET button at the back of the device. Hold it while you plug the power back to the device. The Power LED should be flashing rapidly.
- continue to hold the RESET button until you see four of the six LEDs flashing in a pattern (takes about 5-6 seconds). Release the pin and wait until all LEDs stop flashing
- put the handset back on-hook

If you're having issues dialing DTMF digits (when using calling cards, dialing phone extensions, etc) go to the SIP menu then OOB Signalling tab:


 
Change the Send Out-Of-Band Telephone Events to SIP INFO then click Save OOB settings at the bottom and power cycle the adapter. If that still doesn't help, try the other options for that setting.
