I've just been playing with this myself. <br>
<br>
There is a function, uac_auth, in the uac module which can be used to
authenticate a challenge from another SIP server. Unfortunately it has
the following problems:<br>
<br>
1. Does not handle increment of the cseq. At least in my experience
this causes authentication failure, you may have better luck.<br>
2. Missing quotes in the auth header sent by the other server causes parse errors.<br>
3. Digest comparison is case sensitive (DIGEST in auth header causes parse error).<br>
<br>
2 and 3 are easy to fix but 1 is a major problem for SER as there is no dialog state kept between requests.<br>

Hi,<br><br>I was wondering how I can route my SER users to other<br>SIP servers, without need of authentication to other<br>server.<br><br>I mean this:<br><br>My User -> Auth -> My SER<br><br>My SER -> Auth -> Other SIP Server
<br><br><br>My User --------make call--------> My SER<br>--------route call-------> Other SIP Server<br><br><br>Thank you.<br><br>Kaveh<br><br><br><br><br>__________________________________<br>Yahoo! Mail - PC Magazine Editors' Choice 2005
