Afaik, Linksys SPA9xx series phones had possibility to subscribe to group on their PBX, SPA9000.<div>When you press a group pickup soft key you would see a displayed info about who&#39;s calling who, and you could intercept the call.</div>
<div><br></div><div>FS only send NOTIFY messages to phones that have subscribed to certain extension, regardless of the call groups (standard rfc 3265 and 4235 type presence). Phones generally light LED buttons in order to display the status of the watched extension. With snom phones I have seen that it&#39;s possible to get the display of the call in progress before picking the call up (that&#39;s about what you want - A calling B).</div>
