<P><FONT SIZE=2>Just internally speaking for 20 users with very little room for growth you could purchase a T100P (T1 card) from Digium. Place the T100P it in the Asterisk server. Connect the T100P to a Zhone Z-Plex channel bank (or any other supported channel bank). The channel bank will break the T1 out in to 24 analog handset ports. Ports you could plug any analog phone in to. </FONT></P>
<P><FONT SIZE=2>Next you worry about how to connect Asterisk up to the PSTN, using ISDN, PRI, or what ever is available in your area. It will necessitate the purchase of another card, something Digium can provide, but there are other options out there such as the ISDN cards supported under Linux. Actually if you have good bandwidth without any telephony cards you could choose PSTN access through any number of VoIP providers using SIP and IAX protocols.</FONT></P>
<P><FONT SIZE=2>Hope this helps. Post a little more details and someone will jump in and lend you a hand, or contact me off list and we can discuss further. Good luck,</FONT></P>
