>                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-30376
>             Project: Asterisk
>          Issue Type: Bug
>      Security Level: None
>          Components: Resources/res_pjsip_pubsub
>    Affects Versions: 19.7.1
>            Reporter: Sébastien Duthil
>            Severity: Major
>              Labels: webrtc
>
> Given I have two PJSIP WebRTC endpoints A and B registered
> When A disconnects
> Then B is unregistered on Asterisk
> I can reproduce the scenario with Asterisk 19.7.1 and the configuration given in the [WebRTC tutorial|https://wiki.asterisk.org/wiki/display/AST/WebRTC+tutorial+using+SIPML5] (using two endpoints {{webrtc_client}} and {{webrtc_client2}}) and two instances of the [SIPML5 WebRTC client|https://www.doubango.org/sipml5].
> The disconnection by pressing the "logout" button on SIPML5 does:
> * send a SIP REGISTER with {{Contact: expires=0}}
> * receives the SIP ACK
> * close the SIP Websocket
> Here are the logs of the WebRTC connection for both accounts:
> {noformat}
>   == WebSocket connection from '192.168.121.1:53748' for protocol 'sip' accepted using version '13'
>     -- Added contact 'sips:webrtc_client2 at 192.168.121.1:53748;transport=ws;rtcweb-breaker=no;x-ast-orig-host=df7jal23ls0d.invalid:0' to AOR 'webrtc_client2' with expiration of 200 seconds
>   == Endpoint webrtc_client2 is now Reachable
>   == WebSocket connection from '192.168.121.1:53750' for protocol 'sip' accepted using version '13'
>     -- Added contact 'sips:webrtc_client at 192.168.121.1:53750;transport=ws;rtcweb-breaker=no;x-ast-orig-host=df7jal23ls0d.invalid:0' to AOR 'webrtc_client' with expiration of 200 seconds
>   == Endpoint webrtc_client is now Reachable
> {noformat}
> Here is the Asterisk console when disconnecting {{webrtc_client}}:
> {noformat}
>     -- Removed contact 'sips:webrtc_client at 192.168.121.1:53750;transport=ws;rtcweb-breaker=no;x-ast-orig-host=df7jal23ls0d.invalid:0' from AOR 'webrtc_client' due to request
>   == Contact webrtc_client/sips:webrtc_client at 192.168.121.1:53750;transport=ws;rtcweb-breaker=no;x-ast-orig-host=df7jal23ls0d.invalid:0 has been deleted
>   == Endpoint webrtc_client is now Unreachable
>     -- Removed contact 'sips:webrtc_client2 at 192.168.121.1:53748;transport=ws;rtcweb-breaker=no;x-ast-orig-host=df7jal23ls0d.invalid:0' from AOR 'webrtc_client2' due to shutdown
>   == Contact webrtc_client2/sips:webrtc_client2 at 192.168.121.1:53748;transport=ws;rtcweb-breaker=no;x-ast-orig-host=df7jal23ls0d.invalid:0 has been deleted
>   == Endpoint webrtc_client2 is now Unreachable
> {noformat}
> We can see that {{webrtc_client2}} is disconnected as well.
> We have successfully worked around this behavior in Asterisk 19.7.1 by reverting the patch for ASTERISK-30244.
