If it's any solace to you, there is no way I know of that one can do 
supervised call transfer (what you describe above) on an ATA-186. 
The "#" key trick (appending a "t" on your Dial statements) allows 
you to transfer, but it's an unsupervised transfer.  That trickery is 
done 100% in Asterisk, so you may be able to hack the source code to 
get it working with some different technique.

The workaround is:

  - call party #1, establish call
  - hit flash, dial new number, hit # (the # is locally interpreted by 
the ATA as "finished dialing" character)
  - talk to the third party; tell them a call is about to come in.
  - have the third party hang up
  - hit flash again, bringing you back to party #1
  - hit "#" and type in the number of third party, type "#" (this 
time, interpreted by Asterisk as "finished dialing" character)
  - hang up

Sucks, doesn't it?
