I have an ATA that has a problem on second line.
It's properly (I suppose) configures, it's registered on CCM with both ports (using mac-address shifting mechanism).
ATA is on same vlan as CCM.
When I call DN on first line all it's ok.
When I call DN on second line, phone ring until I reply the call, then it send suddenly a busy tone.
The same thing happen when I call from the phone.
- to change DN
- to invert phones between port 1 and 2
- to change firmware
- to change ATA (!!)
But the problem remain...
I think that it can't be an HW problem, because it happens with different ATA.
any suggestion will be appreciated.

Have a look at these two good posts that relate to this exact issue;

Hope this helps!
Hi Rob, thanks for your reply, sorry for my poor search :-(
In any case, I've tried to set LBRCodec to 0 or, leaving it to 3, set bit 21 in ConnectMode to 0, but the problem remains.
I think that I can't see something (sorry).
Sorry, I've solved.
I've changed Region default enconding and changed Default Pool from ata configuration.
Thanks a lot.
Great work :) I'm sorry if it sounded like my answer indicated that your search was less than stellar. Not at all the case. I remembered reading this one due to the outstanding answer from Paul!
More than glad to be of some small help here :)
