      Security Level: None
          Components: pjproject/pjsip
    Affects Versions: 13.21.1
         Environment: Sangoma 7 (Centos 7) updated as far as it can be as of the date of this post. 
            Reporter: ADTopkek


- I was on a conference call using the default SIP client on android phones. 
- My extension is using PJSIP with 3 contacts
- I had connected to the conference call by dialing an internal number to enter the conference and I was on the LTE network
- I was walking and went into an LTE deadzone. My phone showed "Signal lost".
- It switched to WIFI
- After the conference ended my extension showed busy but was not on DND
- I checked "pjsip show channels" and got this:

  Channel:  <ChannelId........................................>  <State.....>  <Time.....>
      Exten: <DialedExten.............>  CLCID: <ConnectedLineCID.......>
==========================================================================================

  Channel: PJSIP/1170-0000612b/ConfBridge                        Up            00:33:34   
      Exten: STARTMEETME                 CLCID: "" <>

  Channel: PJSIP/1170-0000630f/ConfBridge                        Up            00:10:38   
      Exten: STARTMEETME                 CLCID: "" <>



My extension has a stuck channel in the conference bridge. I assume its because it completely lost signal on the LTE so no end signals were sent. I called a 2nd time to replicate it.
