  • Deepak,

    This is commonly a wrong password on the client-side. That is, the device attempting to call Asterisk is failing an authentication challenge for one reason or another.

    For anyone to help you, you would probably need to post your sip.conf configuration (full) and screenshots of your soft/hard client configuration.

    Obviously you would want to use a fake password and sanitize IP
    addresses if necessary.

    Thanks,

  • Hello Deepak,

    601;tag/498fbd

    is the 111.118.185.107 your server IP? it could be a client trying to authenticate as Rusty suggest or an attacker attempting to gain access, if you want to find out what IP address that request is coming from do the following command. make sure you have tcpdump installed.

    tcpdump -lni eth0 -f “udp port 5060”

    monitor your server to make sure you catch the attacker, also you could do

    tcpdump -w capture.cap

    and analyze it with wireshark.

    Thanks, Motty
