Reading about SIP made it seem like latency alone is not an issue, aside from delays which impact verbal communication as previously mentioned. What is going to be much worse is jitter and packet loss. You can eventually get used to a significant delay, but dropped calls and chopped sound renders the service useless.

Interesting that you say that about sip. We had a client that would useitfor sip on ships all the time. It wasn't the best but it worked. Pingtimeswere between 500-700ms.It really depends on your expectations - or more to the point, your end-users' expectations. I've tested SIP in the lab up to 2000ms RTT. The protocols all hang together and keep working, but it's obviously very much in walkie-talkie mode, you can't hold a normal duplex conversation. 500ms there's more of the talking over each other / "sorry, you go" / "no, you go" dance, but it *is* workable. If your end-user is expecting land-line replacement though... Regards, Tim.
