If used in the context of voice-through-internet, then yes.

But it may still be useful within a voice carrier.  Think of how voice 
carriers currently run their voice circuits over ATM.  You don't have an 
ATM circuit going all the way to your home.  If carriers want to 
eventually merge their voice and data infrastructures, then voice-over- 
MPLS sounds like something they may want.

But I don't think there's any need for the IETF to get involved in such 
development, since the only IP-related component would be managing the 
LSP itself, and existing protocols are adequate for that task.
