[OpenSIPS-Users] use of scenario_id in b2b_init_request

[xaled at web.de]

Hi Vlad,

thank you, I missed the $b2b_logic.scenario variable that can be used to differentiate logic within route[b2b_logic_request]. Now it is clear to me.

It would be good to include it as an example in the B2B tutorial or B2B module documentation.

Greetings,
Xaled

Hi Xaled,

The scenario ID is just a transparent identifier for the current B2B session. You may use it to identify which session belongs to which of your B2B scenarios. You can see this value in the output of b2b_list MI function and also you can retrieve it in the script with $b2b_logic.scenario (this may be useful if you use a single B2B request route, as in the example here: [1]).

Another purpose of the "scenario_id" parameter of b2b_init_request() is to be able to choose the internal topology hiding scenario, by providing the special value "top hiding".
