[Asterisk-Users] Does Digium TDM400P + X100P make a switchboard?

[a1s1]

Hi all users,

Can build a switchboard with TDM400P + X100P?

I need a receptionist to pick up the incoming calls and transfer them to 
appropriate employee.

Do I need those Nortel telephones for this or Panasonic KXTD kind of phones? 
Can I use an ordinary touch-tone phones to transfer the incoming calls? 
Can I put someone on hold with an ordinary phone? 
What do I dial to do these things?

Thanks to all.
Agron.
