Dan,
A number of studies have been done that describe telephone user expectations. Interestingly enough, these expectations differ greatly depending on the situation (landline vs mobile, local vs international, etc.) I am aware of a specific target, but I don't recall the source. I recollection is vague on this but I seem to recall something like 300ms. Hence my prior concern over back to back H.323/SIP and RSVP negotiation overhead.
regards,
-Walter
