Minimum budget usually screws you for future expandability. If you buy a 3 cylinder car for less than a full size car you can't go towing a moving trailer. If you for see the growth later on to need 11 phones you may quickly be on the look out to change base technologies to a T1 interface and channel bank(s). Currently to get 11 analog phones on a system with the analog boards you would be using 3 4 port TDM400 cards at $305 each. So $915. If you don't mind using ebay for the channel bank, you can occasionally find a good one that goes under $400, and you add on the $500 T100P card and have 24 phones as a possibility. Of course if you have 11 phones, you probably have nearing 6-8 lines and need to start thinking of when you will need to switch to T1 from the Telco to cut the cost of all those analog circuits and to get the added benefit of the DIDs and other T1 call features. So you would then be looking at either adding another $500 T100P card, or you could have went ahead and bought the $1500 card in the beginning and have enough ports and channels in your machine to take you past where your company will expand in the next couple of years. I don't think there is yet a real market for used Digium equipment and so I'm not sure how well your hardware will resell when you want to upgrade. -- Steven Critchfield <[EMAIL PROTECTED]> _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
