in the last version you can attach variables to dialog and they are 
stored in database -- but that requires you to upgrade. Also, devel 
version saves the profiles in database, in a json format.

What you can do with 3.0.x:
- use sqlops to write to db table the info you need -- you would have to 
update db based on call events, such as initial invite: insert record to 
db; 200ok to initial invite, confirm the dialog in the record; bye: 
delete the db record; you need to delete also for the case of negative 
reply to invite. You can use rtimer to delete old records (those that 
don't get bye). This is pretty much what dialog module does, but hides 
it in the c code -- all doable in the config
- use htable module to store the details in memory instead of a db table

In summary: upgrading to 3.2.x makes your life much easier. Next major 
release comes with a better dialog storage, you may want to play with it 
as well.

Cheers,
Daniel
