[Users] Multi Call Legs Accounting

[Daniel-Constantin Mierla]

Hello,

as i see in your failure route you close mediaproxy nat handling -- try 
to keep it on. ALso, the contacts in redirect message might be natted 
even when initial destination wasn't -- you have to deal with this case 
as well (start nat handling).

Cheers,
Daniel
