T46G + EXP40

hello, I use a freepbx with my phones.

I would like to make transfer (extension *2) using my EXP40 modules.

On my EXP40 I have :
Type=BLF
Value = 730
Label = 730
Lign = Lign 1
Extension = *2

but its not working, as if I type "*2 730"

It is possible to make that with my EXP40 ?

regards.

Jean-Michel
