<div class="WordSection1">
<p class="MsoNormal">Just upgraded to Asterisk 14.4.0 and verified it’s happening on this version. Previously ran tests on 14.2.1 with the same behavior.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We are using AMI to tell Asterisk to perform a Transfer (really a blind transfer).<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">When we perform this with a chan_sip endpoint, everything works fine for both success and failed transfers.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Success receives a NOTIFY with a “Subscription-State: terminated” and SIP/2.0 200 OK. Asterisk responds with an OK to the other end. Then, I see the SIP trace showing Asterisk ending the call (BYE).<o:p></o:p></p>
<p class="MsoNormal">This success all happens at the same time we see an AMI Event with the TRANSFERSTATUS of SUCCESS.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Failure condition with chan_sip. Again, working correctly.<o:p></o:p></p>
<p class="MsoNormal">Sends the REFER packet, receives 202 Accepted, receives a NOTIFY of Trying, replies with OK (response to NOTIFY). Then, Asterisk receives a NOTIFY with a SIP/2.0 404 Not Found, replies with OK.<o:p></o:p></p>
<p class="MsoNormal">When the NOTIFY 404 Not Found is processed, Asterisk sends an AMI event with the TRANSFERSTATUS of FAILURE.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">With PJSIP, it seems as though the success/failure of the Transfer dial plan command occurs when it sends the REFER. It never waits to know if it succeeds or fails.<o:p></o:p></p>
<p class="MsoNormal">Looking at the PJSIP messages, this TRANSFERSTATUS is sent even before the other side has responded with the 202 Accepted packet.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">When logging the PJSIP messages, I see the so valid number case sends the REFER, receives 202 Accepted, but the trace doesn’t write the Notify/OK response with the Verbosity and PJSIP debug enabled.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">For failures, I do not even see the 404 Not Found in the log. Asterisk replies with a TRANSFERSTATUS of SUCCESS when the other end sends the 404 Not Found.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Is the correct next step to submit an Issue?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Dan<o:p></o:p></p>
