[Asterisk-Users] softphones

[Joao Pereira]

Hi,
can someone tell be about some good and free softphones?
Are they easy to use by non-tecnical users?
Can someone share their experience about the implementation of VoIP
softphones in a company?.... because usualy people dont want to make changes
in the way they work.... I would like to know a way to convince peaple in my
company to use them.

Thanks
