Enabling `100rel`(PRACK SIP Message) is not sending CHANNEL_HANGUP while device declining the call #2365

Open premkumarramasamy opened 8 months ago

premkumarramasamy commented 8 months ago

Describe the bug I am facing one issue with option enable-100rel option(we have enabled this in external profile). When this option is enabled FS is not generating CHANNAL_HANGUP event. Scenario is like this: Call is established from FreeSWITCH and it is declined by the device, we are getting 486 response from the device, upon this FS is not generating CHANNEL_HANGUP event. Is there any open issue with this behaviour or am I missing some config? Without this option FS is generating the events.

To Reproduce Steps to reproduce the behavior:

  1. Register a Event Socket Library using any of the available tools/library
  2. Please a valid dial command in fs_cli to reach a device registered to FS/SBC, which will generate events and they are published to event socket
  3. Decline the call from the device, Device should send 486 to FS, ideally this should generate a CHANNEL_HANGUP event, which is missing when enable-100rel flag enabled in the dialplan.

Expected behavior CHANNEL_HANGUP event should be sent to event socket client registered

Hello!

I think that our case is also related to this issue; when we enable 100rel on the external profile (port 5080), the 486 Busy Here status is not forwarded to the internal profile. When we turn off 100rel, everything works as it should. In the trace screenshot, the internal FS leg is on port 5060, and the external leg is on port 5080.
