-too many incoming messages- too many authentification failures- too quick (abnormal) message receptionsBlocked devices and users can be reenabled anytime by issuing the “delbanned,ip” or “delbanned,all” command on the Console port.Device IP/user caching:For speed considerations, the mizu server can cache device login information for a time so it will not ask again for authorization for everyREGISTER or INVITE request. This means that it can happen that you change the user credentials and the user is still able to login with its oldusername/password or inverse: the user enters the correct credential but will be still blocked for a time. This can be controlled by the“cacheregistrations” global config variable.-request (and verify?) as much data from your subscribers as necessary (country, email address, etc)-passwords are stored in clear text in the user table by default (md5 checksum option is also available). Make sure that your database server cannotbe stolen, hacked, etc.-make sure that all users has a strong password-set max amount, max ports for users-set the “enforcestrongauth” global config option to true-check your traffic on a daily basis or setup scheduled tasks to check abnormal traffic amounts and notify you by sms or email-setup the allowed ip and trusted ip properly (especially for the http api)-check proper dtmf input in your ivr scripts5.87. Ringtone for IVR forwarded callsCan be controlled by the playivrfwdringtone global configurationWe have 4 options here:0=no ringtone from the server (instead we can play any file directly from IVR). In this case if there is no other IVR file playback in progress, theclient can hear the ringtone generated by the called endpoint1=generate ringtone on ring received if there are no other IVR playback in progress (in this case the client will hear ringtone even if the calledendpoint is not generated –i.e. it just sends ringing message in signaling). This is the default setting.2= generate ringtone on ring received even if other file playback is in progress (stopping the old playback)3=generate fake ringtone immediately after call was sent to routing
