Ivan,Actually a simpler approach will be to use t_wait_for_new_branches() instead of that t_write function, it should do the same trick (postponing the deletion of the transaction), but without any side effects.

I'm 100% the transaction is not deleted before the end of the route. And try to use the unix sock flavor for the function, not the fifo one. DO NOT use the sleep, you will block your whole opensips.

Regards, Ivan пн, 17 окт. 2022 г. в 09:38, Bogdan-Andrei Iancu <bog...@opensips.org <mailto:bog...@opensips.org>>: Hi Ryzhik, Right, the transaction must be forced to stay until you are done with a final reply. Unfortunately there is no clear way to do this from script (this may be subject of further small improvements), but you can try taking advantage of the `t_write_req` [1] for this purpose, even if you do not have to actually write anything to outer world - just fake it.

Regards, Ivan. пн, 10 окт. 2022 г. в 17:04, Bogdan-Andrei Iancu <bog...@opensips.org <mailto:bog...@opensips.org>>: Hi Ryzhik, Without a t_relay() it makes not much sense to have an dialog structure at all - the dialog module in opensips is actually design for proxied calls, not for UAC calls. IMO, you should keep it a transaction level, by sending replies back only. When getting the INVITE, put its call-id into a DB table (to keep only the "active" session) together with a lifetime / expiration time. When getting a CANCEL, update the table (set lifetime to 0), to know it is terminated. And use an simple external script that keeps scanning the DB for (1) sending 487 Terminated via MI if the record has 0 lifetime or (2) send a 408 Timeout via MI if the lifetime exceeded. In a similar way you can handle the BYE - send back 200OK for the BYE and set 0 in lifetime, to send a 487 canceled back Regards, Bogdan-Andrei Iancu OpenSIPS Founder and Developer https://www.opensips-solutions.com <https://www.opensips-solutions.com> OpenSIPS Summit 27-30 Sept 2022, Athens https://www.opensips.org/events/Summit-2022Athens/ <https://www.opensips.org/events/Summit-2022Athens/> On 10/10/22 4:33 PM, Ryzhik Ivan wrote:Hello! My opensips version is 3.1 with tm,dialog and rtpengine modules. On incoming INVITE i'm creating an early dialog with 183 replies and i'm playing audio to caller with rtpengine, no t_relay() on this step, OS is acting as UAS endpoint. If the caller cancels the invite with a CANCEL message - all works great. But some users terminate dialog with BYE message. 1) on BYE with to-tag OS can't find dialog with match_dialog(), because to-tag presents. 2) if i use load_dialog_ctx($ci) - it is possible to handle BYE. 3) in early dialog termination with BYE we also need to send final response to the INVITE transaction. Maybe I did something wrong, but I can't handle the final response to INVITE in this case. _______________________________________________ Users mailing list Users@lists.opensips.org <mailto:Users@lists.opensips.org> http://lists.opensips.org/cgi-bin/mailman/listinfo/users <http://lists.opensips.org/cgi-bin/mailman/listinfo/users>
