3/10/09Privileged and Confidential Page 21 Putting it all together  SUMMARY When call comes into trader ring group 1)All traders know what line the call is coming in 2)All traders can see line + callerID concatenated in LCD 3)Trader who picks up call can hang up phone without hanging up on customer or broker since “x” option is used in Meetme(). Therefore, no hold button is necessary. 4)Whenever a single user is in meetme, the bridge will blink in “ringing state” reminding the traders that someone is on hold. “M” option enables music on hold in single participant mode. 5)As soon as traders “picks up” line. Dev state will change to “inuse” and blf key will change from fast blinking to solid.

3/10/09Privileged and Confidential Page 23 Putting it all together Usage Example: Call Barge with XML Barge Notification exten =>s,1,NoOp(Barge feature) exten => s,n,Set(CALLER=${CALLERID(num)}) exten => s,n,System(/etc/asterisk/scripts/barge.php ${MACRO_EXTEN:2} ${CALLER} public) exten => s,n,NoOp(VAR: ${bargmm}) exten => s,n,Goto(${bargmm},1) exten => s,n,Hangup() exten => _1X.,1,MeetMe(${EXTEN:1},qdA,683386) ;Original call members exten => _1X.,n,Hangup exten => _2X.,1,MeetMe(${EXTEN:1},aqx,683386) ;Extension who is barging exten => _2X.,n,Hangup

3/10/09Privileged and Confidential Page 24 Putting it all together Summary  This assumes a simple call scenario between two parties, then a third party that wants to barge, so he will press the xml key (instead he could dial a dial-plan feature code) with to one of the other two parties and following things will happen:  The two parties will be transfer to a conference room.  A message is displayed in the phone screen notifying who is the extension that is barging, only for phones Aastra 55i and 57i.  The aastra phone menu is modified and a new screen is displayed offering the possibility of locking the room disabling the possibility of barging to any other extension.
