Dahdi transfer

Hi! I have some troubles with my dahdi card… I can’t do an “in-call” transfer… The code is supposed to be ## but nothing is done when I dial those keys… Any suggestions? I don’t know where to start… I’m really new to asterisk…

Thanks!

What version of FreePBX? What version of Asterisk? Distro or built by hand. What kind of phones? What kind of DAHDI card?

I’m running asterisk 1.8, with freepbx 2.10… My analog phones are panasonic wireless phonoes… It’s a distro (AsteriskNow) upgraded by hand… My DAHDI card is a TDM410P with two FXO (1&3) and two FXS (2&4)…
