Hello,

We use Asterisk Realtime for our billing software. 200+ installations of Asterisk with Realtime, but I see this for the first time.

Asterisk 1.4.17, Addons 1.4.5, No patches, no NAT - just plain simple installation.
With debug I can see:

Notice update: UPDATE devices SET ipaddr = '0.0.0.0', port = '0', regseconds = '0' WHERE name = '109'

Correct behaviour is: UPDATE devices SET ipaddr = '213.164.10.178', port = '60854', regseconds = '1201750701' WHERE name = '109'

Why update to 0.0.0.0 is executed? It makes devices unreachable. When device reregisters - it becomes available for short time - then again - update to 0.0.0.0. Why it is happening?


For temporaly solution i had to patch res_config_mysql.c at line 342, added such lines:

if ((!strcmp(newparam, "ipaddr")) && (!strcmp(buf, "0.0.0.0"))){
ast_log(LOG_DEBUG,"MySQL RealTime: Avoided to update %s to %s !!!\n", newparam, buf);
ast_mutex_unlock(&mysql_lock);
return -1;
}
