asterisk users - Jul 2003 - three way calling and cisco ata 186

I use cisco ATA 186 ( Version: v2.16 ) with sip protocol and
asterisk  as pbx. I need feature called as 'three way calling' or 
'transfer with consultation'. Registering,calling and 'blind
transfer'
work fine.

Is this feature provided by sip clients or by asterisk itself ?
What I have to configure in ATA   and what keys I have to press
on my phones ?

Three way calling is enabled by setting  bits 28-29 to 10
  ( Select the Cisco VG248 Style for mid-call services.
  as described at 
http://www.cisco.com/en/US/products/hw/gatecont/ps514/products_administration_guide_chapter09186a00800c4d1f.html#42433
But it seems not works,I always get conference call with 3 persons.

Same here - and if you hang up, the call is not transferred...
Something goes wrong when using the Hook-Flash with ATA/Asterisk.

Any solutions out there?
