[asterisk-users] Good phones for outside of the office?

[Warren (mailing lists)]

I am looking for phones that work well (or at all) when outside of the 
network and behind a router, such as at someone's home or in a hotel. 
My Polycom IP601s do not seem to be up to the task, so I am hoping that 
there is a good alternative for my outside sales people to use to talk 
to my asterisk server.

Thanks in advance,
Warren
