<DIV>Hi!</DIV>
<DIV> </DIV>
<DIV>Searching at google, I found out that someone had a very similar problem to mine and posted it here under the subject "Outgoing calls to SIP provider".</DIV>
<DIV>Unfortunately I couldn't find how the problem was solved - if it was. Is it an Asterisk's bug? Have I done something wrong?</DIV>
<DIV> </DIV>
<DIV>Thanks,</DIV>

<P align=left>I have a group of users configured as extensions in *.These users are registered with a SIP Proxy Server and can receive calls very well. The problem happens when any user tries to make an outbound call. The proxy replies with a "401 Unauthorized" and * don't try another INVITE including credentials.</P>
<P align=left>Here is part of the content of sip.conf.</P>

<P align=left>Here is part of the content of extensions.conf.</P>
<P align=left>;This part is working fine<BR>[sip]<BR>exten => 999,1,Dial(SIP/user1,,tr)</P>

<P align=left> </P>
<P align=left>When I dial the number 812345 from my SIP Phone, this is the message sequence<BR>Phone -> Asterisk: INVITE sip:812345@*domain SIP/2.0<BR>Asterisk -> Phone: SIP/2.0 407 Proxy Authentication Required<BR>Phone -> Asterisk: ACK sip:812345@*domain SIP/2.0<BR>Phone -> Asterisk: INVITE sip:812345@*domain SIP/2.0 (with authentication header)<BR>Asterisk -> Phone: SIP/2.0 100 Trying<BR>Asterisk -> Proxy: INVITE sip:12345@mydomain SIP/2.0<BR>Proxy -> Asterisk: SIP/2.0 401 Unauthorized<BR>Asterisk -> Proxy: ACK sip:12345@mydomain SIP/2.0</P>
<P align=left>The next message I would expect is another INVITE from * to the proxy with the authentication header.<BR>Why * hasn't send it? Can someone give me a help?</P>
