ATA - Second Port Problem

Answered Question
Mar 12th, 2008

Hi all.

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.

I've tried:

- 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.



I have this problem too.

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.

Hi Daniele,

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 :)

Take care,
