<br>
I look up the GSM number and provider information in a database and sets <br>
the headers.<br>
<br>
dlg_manage();<br>
$du = "sip:" + $dbr(ra=>[0,0]);<br>
$tu = "sip:"+$rU+"@"+$dbr(ra=>[0,0]);<br>
$ru = "sip:"+$rU+"@"+$dbr(ra=>[0,0]);<br>
uac_replace_from("sip:"+$dbr(ra=>[0,1])+"@EXTERNALIP");<br>
<br>
After this the call goes to a failure_route to do uac_auth()<br>
<br>
Now my problem is that this works with the providers Asterisk server.<br>
But if the call is send to the providers Kamailio server, authentication <br>
is rejected.<br>
<br>
Removing uac_replace_from makes the call accepted on the Kamailio server<br>
<br>
The only possible problem I can see is that the first INVITE without <br>
authentication, has correct From header.<br>
But the second with the nonce and auth, uses the wrong From header. Thus <br>
two different From headers in the same SIP dialog.<br>
<br>
Unfortunately uac_replace_from is not allowed in failure_route, so I <br>
could test if this is the problem.<br>
<br>
Is the two different From headers a problem, and how could that be fixed.<br>
