Mike and Brian, Thanks for the information. Between when I sent the original and received your responses, I found your Jira entry and sent something to Aastra. Not really intending to get anything from them. But thanks to both of you!

We have been working with them to resolve it but as of yet they have failed to deliver a working firmware for their phones.

I have 2 Aastra 6731is and a 51i and trying to get SCA working. I'm experiencing problems similar to the Cisco thread from last month - outgoing calls implement SCA well. Incoming calls ring all lines and appearances work, but when one phone is answered, the line appearances are removed from the remaining phones. I am not attempting to use any DNS. My configuration has all three phones plus FS on a local LAN. Nothing too fancy. Each line is configured for Broadsoft SCA and SCA bridging is enabled globally for the phones. Trying to update/replace an old phone at my church.
