asterisk users - Apr 2005 - What is the best client's protocol for my softphones

Hi all,
    What is the best client's protocol for my softphones in Windows pcs? and
    what is the best way for connecting clients, I meant should I use one
    protocol for all the clients or some mix (SIP/IAX/oh323) of protocols?
what
    is better?
    Thanks in advance

I would say IAX. If you only use 1 protocol for your clients, they can
native-bridge, so Asterisk won't stay in the path.
