------------------------------------

             Summary: Subscriptions Persist After Expiration and TCP/TLS Disconnect
                 Key: ASTERISK-27612
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-27612
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: Channels/chan_pjsip, Resources/res_pjsip_pubsub
    Affects Versions: 13.19.0, GIT
         Environment: Fedora 23
            Reporter: Ross Beer


BLF subscription persists after Expiry reaches 0:

{noformat}
Endpoint: <<ENDPOINT>>/"CALLER ID" <03455610561>
Resource: <<OTHER ENDPOINT>>/dialog
  Expiry:        0  313531363537303339313432303931-938sotuzwa58
{noformat}

When using TCP/TLS connections, these cause warning messages to be displayed:

{noformat}
[2018-01-23 09:43:43] WARNING[180033]: pjproject:0 <?>:             tlsc0x7f666c089428 TLS connect() error: Connection refused [code=120111]
[2018-01-23 09:43:43] WARNING[180033]: pjproject:0 <?>:              tsx0x7f6664147df8 Failed to send Request msg NOTIFY/cseq=29928 (tdta0x7f66900173e8)! err=120111 (Connection refused)
{noformat}

To resolve this issue two things need to happen:

1) When an inbound subscription expires, remove the active subscription references

2) When a TCP/TLS connection disconnects, expire any active subscriptions for that connection.
