Joining vicidial_agent_log and vicidial_log

Is there a recomended method of joining the calls sent to an agent (in vicidial_agent_log) and the calls reported in the system call log (vicidial_log)?
It seems to me that the uniqueid field from the vicidial_log table should be stored in the corresponding records in the vicidial_agent_log table. Is there a reason this was not done?
In the absence of that field, is there a recommended SQL join that can be used to join the entries in these two tables?
