Hello all, Sending this question one more time, hope i can’t get some ideas to move forward.
We are trying to implement the « REFER » method in opensips 3.3. we used this documentation : openSIPS | Documentation / Tutorials-B2BUA<https://eur03.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.opensips.org%2FDocumentation%2FTutorials-B2BUA%23toc15&data=05%7C01%7Camel.guesmi%40orange.com%7C181723563d0c43181dce08db9429c16f%7C90c7a20af34b40bfbc48b9253b6f5d20%7C0%7C0%7C638266679269197623%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=icy4eVaC2QsWW%2FZRcnUT0xQfGYAPYDUNiJyE2pW7NtY%3D&reserved=0> When we detect a REFER method, we are excuting those functions : b2b_send_reply(202, "Accepted"); # Example: Send NOTIFY request $var(destination) = $hdr(Refer-From); $var(message_body) = "This is the message body of the NOTIFY"; send_request("NOTIFY", $var(destination), $hdr(Refer-To), $var(message_body)); # create the client entity corresponding to # the user specified in the 'Refer-To' header b2b_client_new("referee", $hdr(Refer-To)); # bridge the referrer's peer with the referee b2b_bridge("peer", "referee"); #b2b_end_dlg_leg(); With that scenario, we succeeded in transfering a call after the REFER and we are tryning now to implement that process with « Notify » after the REFER (see the flow in the following link). REFER_-_User_docs_2.width-800.png (720×540) (twilio.com)<https://assets.cdn.prod.twilio.com/images/REFER_-_User_docs_2.width-800.png> For this, when we open the new client session, we don’t end the session with the one sending the REFER and we need to detect when the call is accepted by the Callee (200 OK) when we are using that function : b2b_client_new("referee", $hdr(Refer-To)); My question : How can we detect the 200 OK in that B2B mode in order to send the NOTIFY before ending the session with Alice. Thank you very much BR, Amel Orange Restricted
