[asterisk-users] Big time system

[Tarek Sawah]

a Rack of load balanced Asterisk Servers with some customized billing system with a respectable centralized database like MsSQL or Oracle ..External E1 or T1 Gateways instead of TDM cards.. with load balancing?? as the whole operation is COPPER WEIRES .. can't that setup work for them?I'm asking as i'm looking for a similar setup just trying to set it up virtually before we go live.Regards
