there multiple tools that may need script init (localcache, shared 
variables, etc). Of course, once we have the implementation for memchace 
support (memchace server), so of the needs may disappear, but there are 
cases where you want to use the localcache only and you need to init it.

I see your point and I agree with that - personally I had this need also 
and this is why I added in Drouting module the "attrs" field for the GWs 
definition - see 
http://www.opensips.org/html/docs/modules/devel/drouting.html#id272135.

Of course, the same mechanism can be added to several other modules 
(like permissions as you suggested).

In this area I intend to add support for JSON (json.org) to be able to 
structure more info in a single string value - you have a generic attr 
field that may encode multiple values, keys, etc using json scheme. So, 
the idea will be to add the json transformation to extract from the 
encode string a certain attribute.

you mean to get directly CDRs, instead of acc events?

maybe this can be split between stat vars (for counting rules and GW) 
and MI commands (like triggering a routing request from outside).

Ok

like a command to purge the entire content?

but how do you suggest to identify the attributes to be purges as they 
have different names? regexp matching ?

this is something I'm working on - to have persistence across reboot for 
profiles, dialog values and flags.
