in sip.conf general I point to context from_sip and in extensions.conf I have extension 43 defined. I have the impression that it never reaches that context though since the auth failed happens right along.
Let me yet again ask one more thing: Why does * say authentication failed if allowguest=yes is set in sip.conf (it is on by default anyway is it not?)? If it is some sort of extension problem it should at least accept the connection and then throw an invalid extension error or something else.
Or is authentication failed just another * way of telling me that the extension is not setup correctly? Since my IAX guest user is directed to the same context and works like a charm, I strongly doubt that the extension setup is incorrect.
The problem seems to occur only if a SIP client that is registered at another registrar is trying to connect to my *. In my example, my FritzBox!Fon is registered to my t-online account and tries to connect to the * SIP guest account.
You can tell * in sip.conf whether or not it should accept non-authenticated SIP calls (allowguest). Default = yes.
If someone tries to call without any auth-try everything works fine. Some SIP-clients (like FritzBoxFon) try to authenticate with their account though (when using ENUM) which then fails since * does not accept this auth.
I have the same problem, I can’t receive calls because of "Sep 23 18:00:48 NOTICE: chan_sip.c:10918 handle_request_subscribe: Failed to authenticate user “Blabla"sip:email@example.com;tag=451e4d28 for SUBSCRIBE”
Why does the “allowguest=yes” in sip.conf ([general] context) option does not work?
btw i’ve tried all other options to get incoming calls but they do not work too :
