Hi Dears,
I'm trying to configure Kamailio as SBC in multi home mode for Asterisk by
authenticating the inbound SIP registration requests,i'm following this
tutorial
http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb
to achieve this goal. i have modified the necessary changes like the
Asterisk DB URL and the SIP table name and Username and password column and
verified the connection.
My topology like this *Asterisk (192.168.100.10)
<----Internal:192.168.100.1---->Kamailio<---External:192.168.50.1-----> SIP
Phone (192.168.50.2)*
But when trying to register a SIP phone Kamailio does NOT forward the
authentication request to Asterisk and sends 401 Unauthorized error
message.I've attached my config file if any one wants to check it and
thanks in advance.
Best Regards
