<div>We are looking for setting up a small scale calling card operations in USA. and also need a softswitch billing system for post paid clients.</div>
<div> </div>
<div>After looking into the commercial product available in the VOIP market, we decided to adopt an Asterisk based system which could following at a minimum. Following are question to the list:</div>
<div> </div>
<div>1. Can Asterisk based system support both H323 and SIP protocol? I ask this as several of our terminating gateways are based on H323.<br> </div>
<div>2. Is there any commercial or open source software which can have both soft switch, prepaid and post paid calling systems?<br> </div>
<div>3. Is there any Codec convertor available for Asterisk based system to convert say G723 to Gg729 or vice versa</div>
<div> </div>
<div> </div>
<div>Please let me know?</div>
<div> </div>
