I had a similar requirement about 5 years ago for a 24x7x365 adult chat site, except it was for T1s instead of E1s. Back then, the interrupt activity from the 4 cards was strongly advised against. I don't think that is an issue any more. When we thought about it, 4 1u pizza boxes with 1 quad card each made more sense. The dialplan on these "telco servers" just answered the call and dialed the "application server." If a telco server crashed, we only lost 25% of our capacity. Likewise (because we were running at less than 75% of capacity), we could do a "rolling upgrade" of the telco servers without any downtime. When we wanted to upgrade the application server, we changed the telco server dialplan to dial the backup application server. You may want to take a look at external E1/T1 devices like red-fone.com. -- Thanks in advance, ------------------------------------------------------------------------- Steve Edwards [email protected] Voice: +1-760-468-3867 PST Newline Fax: +1-760-731-3000 _______________________________________________ --Bandwidth and Colocation Provided by http://www.api-digital.com-- AstriCon 2009 - October 13 - 15 Phoenix, Arizona Register Now: http://www.astricon.net asterisk-biz mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-biz
