1) A lot of people use openzap in production environements
2) probably, even if openzap doesnt implement it (which I think it does),
you can use call groups to achieve the same results
3) freeswitch has a db application/api that does the same.
4) it sets the "nibble_total_billed" channel variable, which you can use in
your cdrs.
