I'm using an ATA with UC520 for FAX handling and is working correctly.
The codec I use is 711.
Now I want to enable the second port on the same ATA and apply an internal number to it.
I tried with button 2:num but it doesn't work.
If I lift the telephon I hear no tone, the ATA shows a red light and nothing happens.
Can anybody help me?
Do "show ephone summary" - you will see the ATA registers as second ephone with the same MAC address shifted with 01 added at the end. Use this second ephone to configure as you like.
Hope this helps, please rate post if it does!
