<p class=MsoNormal style='margin-bottom:12.0pt'><font size=3
face="Times New Roman"><span style='font-size:12.0pt'>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>
