However, I believe a lab can never fully replicate a production environment due to lack of traffic (generators don't quite get the same results) and that you can never underestimate a user's ability to wreak havoc and do something that no one ever thought of or a sane person would do with equipment.
And of course we have the follies of SIP and NAT, particularly for those of us who have a bring-your-own-internet policy. Recently we've had a rash of customers who upgraded their routers and the upgrade came with a SIP ALG that broke something weird. The weirdest was one where attended intra-office transfer broke, but not outside transfer nor intra-office blind transfer. We don't consider anything production-ready until some customers have beaten on it. We migrate them in the order of beta-aware, not aware but systems we manage and can move back ourselves, and then the rest. -- Carlos Alvarez TelEvolve 602-889-3003 Advanced phone services simplified
