I am trying to make full SBC using mostly opensips components.The call flow
will be like diagram below..
For features like concurrent call limit, call timeout, CDR accounting I
will have to use dialog module in main opensips proxy. For B2bua if I
understand correctly I will have to use another instance. My doubts are ..

1- Since B2bua is dependent on dialog module this architecture will create
dialog twice in shared database (Plan to use real time DB mode for
persistence and display of ongoing calls in real time). Can this redundant
work be avoided?

2- Can concurrent call limit, Session timeout (Prepaid), CDR accounting be
implemented at b2bua instance and leaving proxy free of this burden?
