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.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>Hi!<br>
<br>
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.<br>
<br>
Phones will be connected to the server through the same SIP trunk as this will
be some kind of a "hosted pbx".<br>
<br>
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?<br>
<br>
Your help is much appreciated!<br>
<br>
Chris<o:p></o:p></span></font></p>
