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...
