If you are needing that hard to get ressie like CRT I wouldn't advise using the 800# .. the one time I tried to use it (while dialing the long distance ## on my second phone) I wasted time having to enter my ressie ## and other such information on the 800# only to have my other line answer first. Can't afford to loose precious time. I did my 90 ADR last week .. starting dialing and redialing at 6:55 a.m. and never held more than 10 minutes.
