ISDN : Asterisk in parallel with wires phones

Hi,

I’m new to PBX/Asterisk. Tried to search the forums, but could find any information.

At work, we are 4 employees, and we use ISDN (2 lines). I want to experiment with Asterisk, but I want to use our wired phones in parallel with Asterisk. Will this work?

And is there any way to transfer calls from Asterisk to our ISDN phones? In case I answer a phone and need to transfer the call to another employee.

Last question… what is the “best” IP telephone to use with Asterisk? As a gadget freak, I want many bells and whistles… :smiley:
