<DIV>Hi,</DIV>
<DIV><FONT face="MS UI Gothic"></FONT> </DIV>
<DIV>Recently I am encountering an authentication error when making a phone call
between Asterisks.</DIV>
<DIV>That call is intended as follows.</DIV>
<DIV>(1) SIP_phone2 to Asterisk#2</DIV>
<DIV>(2) Asterisk#2 to Asterisk#3 </DIV>
<DIV>
<DIV>(3) Asterisk#3 to SIP_Phone3</DIV>
<DIV> </DIV>
<DIV>At (2), that is transferring a call such as </DIV></DIV>
<DIV> -- Executing Dial("SIP/211-6da6",
"iax/k0.dyndns.org/302") in new stack<BR> -- Calling using
options
'exten=302;callerid="sip-211";language=en;formats=4;capability=2147483519;version=1;adsicpe=2'<BR></DIV>
<DIV>
<DIV> and encountering following error message:</DIV>
<DIV> </DIV>
<DIV> WARNING[65545]: File chan_iax.c, Line 3838
(socket_read): I don't know how to authenticate
methods=rsa;challenge=196090514;username=iaxtel to 61.125.27.147<BR></DIV></DIV>
<DIV> </DIV>
<DIV>I started to experience this error recently when I upgraded Asterisk a
few weeks ago.</DIV>
<DIV>With another Asterisk, say between Asterisk#2 and Asterisk#1, there are no
such a trouble.</DIV>
<DIV><FONT face="MS UI Gothic"></FONT> </DIV>
<DIV>It is highly appreciated if you let me know where I should examine.</DIV>
<DIV> </DIV>
<DIV>Thank you very much,</DIV>
<DIV>Hiro</DIV></BODY></HTML>
