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.

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.

25
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
