Unfortunatelly good-old Windows based ping is all I can work with before I
actually sign the contract with the ISP. I need to assess rather the service
might be possible before I start throwing money at it (there's no such thing
as an "test account": I'll need to set up an account, pay the instalation
fees, pay one month in advance for the service then pay for the
disconnect!).

Sooo... what might I find using ping? Is there an "good" ping that shows I
can use the link for VoIP? I gues there's no such thing as "bad" ping
showing I can't use the link because ISP's are limiting ICMP traffic?
