asterisk users - Dec 2004 - What is the best commercial soft phone for Asterisk?

Hi all,

What is the best commercial soft phone out there that can be used with
Asterisk?

Is acoustic echo cancellation at the softphone level a real good feature
to have? I do have a bit on an echo problem, with X-lite and Iaxclient.

Regards,

Francois
