I use it also, and the voice quality is tremendous if you allow the
recommended port ranges. I would say that it is far better than our
telephones here in Bermuda.

Hi Jason,

 

I use Skype because its pretty firewall friendly. I understand your
reluctance because of the developers less than pristine past, but the
app is pretty standard VoIP and the nice thing is that its not SIP
dependent, so you don't need an ALG to support it. I don't think it
works in Web Proxy mode, but it will use TCP 80 is that's the only port
you want to allow. Does your corporate network use policy allow VoIP
communications over the Internet?

 

HTH,

Hi Chaps,

 

Someone is trying to make a case for using Skype on our network....now
my instincts tell me that a program designed by the same people who
brought us Kazaa can't be all that healthy for a corporate environment.
So I'm inclined to not allow it (or at least not support it).

 

Does anyone have any experience or opinions on the use of software like
this? 

 

Cheers,

 

Jason

 

P.S.

We currently have an ISA 2004 edge firewall configuration
