Calling card application and bandwidth usage

Hi all,

If I configured Asterisk as a calling card server using the bundled CC application in AAH, would remote SIP clients using my server to terminate calls to my SIP provider, also use my bandwidth for their calls(RTP streams)? Is there a way to make the SIP clients connect their RTP streams directly to my provider’s gateway, but still be monitored and billed by my Asterisk box?


This will work if everyone is not behind firewall.
I don’t know if this could work if client is behind firewall.
