Random busy when calling analog extension on ATA-186.

Hi,

I've connected a brand new ATA-186 to a customers UC520 today, the extensions showed up nicely and after giving them their proper extensions the worked like expected. After a couple of test calls it was clear that about 4 out of 10 of incoming calls came back busy. This was regardless if the calls came from the outside or another internal extension. It was completely random and sometimes 10 calls in a row went through and sometimes 7 calls were rejected with busy signals.

There's five other ATA boxes on this system that doesn't have this problem.

Best regards

Markus

I solved it.

There was still traces from the four FXS extensions that was moved to ATA boxes. Apperently CCA didn't do a good job clearing everything related to the extensions that was deleted. This caused some of the calls to fail with fast busy, after deleting all the traces in cli it works fine.
