Here are a few "look outs"; Using conference rooms will increase your bandwidth requirements. On board Network controllers will affect performance in this "high-use" scenario. 250 simultaneous calls will use about 7.5Mb of bandwidth depending on the codec(s) you use.

Number of "lines" (numbers) is not a limitation in it self unless they are all in use.

A customer of mine wants to connect an asterisk system with 240 to 480 lines to a PSTN switch. To save the costs for E1 cards and the corresponding E1 mainlines he wants to connect the system to the switch by a SIP trunk. Phones will be connected to the server through the same SIP trunk as this will be some kind of a "hosted pbx". Given he finds a provider wich has this much SIP capacity and IP bandwith and no codec conversion is needed - do you think this is possible with pure asterisk on a decent system? Is there anything I shoudl watch out for? Your help is much appreciated! Chris
