Hi, i've identified a bug in PJSIP (and thereby in Asterisk 13): Scenario: UA calling to PJSIP ---> INVITE (in SDP: a=inactive) <--- 183 Session Progress (in SDP: a=inactive) (some conditions are met [a dedicated bearer on LTE is activated], so the UA will activate the Audio-Stream by sending an UPDATE-Request) ---> UPDATE (in SDP: a=sendrecv) <--- 200 OK (to the UPDATE, in SDP: a=sendrecv) What happens now, is wrong: <--- 200 OK (to the INVITE, in the SDP: a=inactive) ---> ACK The 200 OK should be "a=sendrecv", since the original session was activated/updated by the "UPDATE" request. After digging through the code of chan_pjsip/Asterisk, I've found that it's actually a bug in PJSIP and not in Asterisk. Asterisk indicates, that the call is hold during INVITE and upon UPDATE, it indicates that the call was reactivated. Currently, I replace the a=inactive with a=sendrecv in the 200 OK on Kamailio-Proxy, but that's more a dirty hack than a proper fix. I've verified the behaviour with Asterisk and the pjsip-ua from the samples folder (both Version 2.7.1).

Hi, is there any proper way to report bugs? I haven't found a way, to open a ticket on the bug-tracker.... nor to create an account, in order to do so.
