i found sofia_reg_internal.db grow bigger and bigger after FreeSwitch for some time. <br>the change comes from the sip-authentication table inside this db, it always create new record for nonce for the new challenge ('407 Proxy Authentication Required') for the call from registered users.<br>
any one can help how to avoid the db grow, i'm afaid the hard disk will be full along with time...<br><br>Thanks!<br>
