Last Call Return (lcr) Key (for Sylantro Servers)

Using the Aastra Web UI, you can configure the "Last call return" (lcr) function on a key. This feature is for Sylantro servers only.

How it works

If you configure "lcr" 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 “lcr” and the phone dials the last call you received. When you configure an “lcr” key, the label “LCR” displays next to that key on the IP phone. When the Sylantro server detects an “lcr” request, it translates this request and routes the call to the last caller.
