Thank you for such a cool and detailed answer! But I would like to clarify the following:
>Custom headers can be set for each b2b_entity during the entity setup via the extra_hdrs and extra_hdrs_bodies [4] [5]. Do I understand correctly that this only works for initial invites? >For now, the outgoing socket is set by opensips internally. There were some fixes related to this, make sure that you are using the latest opensips version. But I have several sockets and how can I influence the choice? ср, 18 окт. 2023 г. в 15:59, Ovidiu Sas <[email protected]>: > Hello Denys, > > Dialog module should *never* be mixed with the b2b module. > For b2b calls one can use the $b2b_logic.ctx vars [1]. > For b2b tracing use the 'b' scope in trace() [2]. > There are some issues as not all provisional replies are traced [3]. > Custom headers can be set for each b2b_entity during the entity setup > via the extra_hdrs and extra_hdrs_bodies [4] [5]. > For now, the outgoing socket is set by opensips internally.
