What do you mean by see online on conf file?
If you want to route calls only if the account is online you should use javascript.
When you login an account the module will send an user.notify message with its status.
In javascript you can store account status and route if online.
Some configuration options are applied on reload (no restart needed).
Just ask what you need to know.
For example regexroute rules are always replaced on reload.
