Dear all,<br><br>I am am using SER to provide SIP service to my clients, but I would like to allow them to make outbound calls. This is where a SIP VoIP provider comes in. As far as I know, I have 2 possibilities:<br><br>- using IP authentication
<br>- using client authentication<br><br>As for the first one, I only have to forward the INVITE messages, right?<br><br>What I would like to know, is how to use &quot;user authentication&quot;. In this case, it would be transparent to the VoIP provider since it should be treated as a regular SIP user agent.
<br><br>Can anyone help me out?<br><br>Jose Simoes<br><br><br>
