Attended transfer means than you can not perform the following scenario:
A call B and want to talk to C
B call C and tell him that A want to talk to him
B hangup and transfer the call from A to C who can speak directly

This is a rather classical scenario from telephony, and I think it worth getting a SRU in Lucid.

 IMPACT: New users or users upgrading to Lucid, can not perform an attended transfer.
 FIX: Patch derived from upstream asterisk addresses this issue. >>>>
  With the bug, you have the following scenario:
    1. A calls B
    2. B picks up and talks to A
    3. B does attended transfer to C
    4. C picks up, but B still hears ringing
    5. A and B are connected again (AT timeout exceeded on console)
  With the patch, you should have the expected scenario described before.

  We have done quite a lot of testing after applying the patch on our IPBX. We have covered a lot of functionalities.
