[Asterisk-Users] Budgetone 101 phones ? SIP through NAT ?

[Kim Lux]

I'm new to VOIP.  We are thinking of setting up a VOIP system between a
couple remote offices.  I've been lurking on this group for a while. 

What is the consensus on these phones:

I'm confused about the SIP protocol... can a SIP phone be located behind
a NATing firewall ?

When people use asterisk on a broadband connection used for data and
VOIP, do they put the asterisk machine behind a firewall or do they put
the firewall on the asterisk machine ?

Is anyone using QOS throttling when sharing VOIP and data on the same
broadband connection ?  Is it necessary ?  

Thanks.
