ISDN service appears to be in a terminal state, so.....which VOIP studio-to-studio software do you use for sessions? I've got my plan B & C in place, but I am still undecided on my plan-A VOIP solution. If you answered other for either hardware and/or software, please tell me/us what you use. I've selected my Internet solution, I'll need an alternate path for my sessions because summer time construction here in Montana takes out our Internet two or three times a year, often for several days. So I've included my Plan B & C backup strategies in case your are considering something like this too. *** Plan-B (wishful Plan-B) is a satellite uplink (384kbps) that you can use on a retainer basis (read affordable insurance) for VOIP phone patch sessions (http://www.skycasters.com/index.html) *** Plan-C is a telephone line solution from JK Audio (http://www.jkaudio.com/broadcast-host.htm) that is similar to the phone patch studio I built in 1982. Either of these solutions could get your session back on line in minutes if your main Internet connection goes down...although Plan-C isn't likely to win rave reviews compared to Plan-B.
