Size up your need and consider a T1 or E1 interface. You are really close to some markets break even point. Also expanding beyond 8 lines should probably be done only on a digital line. Add to it the ability to have faster ring and hangup detection, cleaner lines, and no concern about impedance matching echo problems. Then you can look at the future growth potential. With a T1/E1 interface already in place, it shouldn't be any real effort or even delay if you want to add more circuits. From the switch side they just turn up a few more DS0's and you coordinate to configure your side as well. No real circuits have to be wired and no new equipment to add. Not to mention a single TE100P card at $500 is cheaper than 2 TDM400 cards fully kitted out. -- Steven Critchfield <[EMAIL PROTECTED]> _______________________________________________ Asterisk-Users mailing list [email protected] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
