Last Call Return Key
Using the Aastra Web UI, you can configure the Last Call Return function on a key. If you configure Last Call Return on a
key, and a call comes into your phone, after you are finished with the call and hang up, you can press the key configured
for Last Call Return and the phone dials the last call you received. When the Sylantro call manager detects an Last Call
Return request, it translates this request and routes the call to the last caller.
