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.
