Why Turrets are great!!!

Turrets come with own SLA/BLA server (TPO) and conference bridge.

Asterisk support for common lamping is ok, but SLA is not great

Turrets support speaker trading – hands free on multiple simultaneous channels

Multiple Handsets with Push to Talk Functionality


Turrets are not for everyone

Not every floor needs turrets Many traders can do without them


Turrets are not for everyone Common Needs:

SLA/BLAOne-Touch BargePrivacy On/OffSLA/BLA to Private Line Common Lamping with call stateDirected Call PickupHands Free Hold


Station Example: Aastra 57i

Aastra 57i with and without modular sidecar


Why Aastra?

Multi Cast Paging Support Well documented and Extensive XML API 802.1x support Superb configurability Good BLF support Excellent Soft Key Features


Putting it all together

Basic Phone Soft Keys:

Barge

Privacy

Page All

Page Group + (ring group)

Intercom + (extension)

Orbit 1-5 (onhold devstate on side car)

Bridge Lines (single user ringing devstate on side car)



Usage Example:

Inbound Ring Group into Bridged Line with contextual device state

Putting it all together SUMMARY

• When call comes into trader ring group1)All traders know what line the call is coming in2)All traders can see line + callerID concatenated in LCD3)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.



Usage Example:

Going from Bridged Line Mode into Privacy Mode

XML Soft Key On Phone:

http://<web_server>/conference_rescue.html?$$SIPUSERNAME$$


Putting it all togetherUsage 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(${EXTEN:1},qdA,683386) ;Original call membersexten => _1X.,n,Hangupexten => _2X.,1,MeetMe(${EXTEN:1},aqx,683386) ;Extension who is bargingexten => _2X.,n,Hangup


Putting it all togetherSummary 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.


Conclusion

It is possible to build very impressive and featureful telephony solutions for the trading room floor with the right partners and goals in mind. Special thanks to IP Trade Networks and Aastra Telecom for all of their assistance.
