<div><tt>Hi John,<br>
<br>
Why do you need the B2B part ? And answering your questions:<br>
<br>
1) B2B is not dialog dependent, but TM only, so there is no risk<br>
<br>
2) It will be more difficult to have them in B2B than in proxy -
those features are more proxy oriented.<br>
<br>

<div>I am trying to make full SBC using mostly opensips
components.The call flow will be like diagram below..<br>
</div>
<div>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 ..<br>
<br>
</div>
<div>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?<br>
<br>
</div>
<div>2- Can concurrent call limit, Session timeout
(Prepaid), CDR accounting be implemented at b2bua instance
and leaving proxy free of this burden?<br>
