[OpenSIPS-Users] B2BUA module - two questions

[Bogdan-Andrei Iancu]

Hi Dimitry,

There are some issues with your script. First you should not use dialog 
and b2b modules in the same time, for the same calls. The dialog module 
is designed to manage calls in proxy mode (calls coming in and being 
proxyed further), while b2b is doing a UAS + UAC call handling (no proxy).

Secondly, once a script get into b2b handling (via b2b_init ), no 
further requests or replies related to that B2B session (UAC and UAS 
sides) will be visible in the script any more - everything will be 
automatically identified and handled according to the scenario. So, it 
is useless to handle and do ACC for sequential request in the script, as 
none will get there.

Last, the acc module can do accounting and transaction or dialog level. 
As there is no dialog state here , use transaction based accounting and 
get access to the requests related to the b2b session via the b2b 
dedicated routes (see b2b_request_route parameter). Better take a look here:
