asterisk users - Oct 2004 - Digum board TDM to Phonejack --Quicknet --Trandsfering calls.

I have succesfully integrated some phonejacks with Zaptels. I am able to
transfer calls from my tdm board to my phonejack (from quicknet) using  the
hangup button (pressing it once). But I am unable to do this the other way
around with the quicknet board.

This works :

Phonejack ----------Digium TDM -------------Phonejack

But,

THIS DOES NOT WORK

Digium TDM to -----------Phonejack ---------- X ( does not work ) --another
extensions with a phonejack

ANY HELP IS APPRECIATED.

Thanks

Francisco
