[Freeswitch-users] Media after hang-up???

Hi Mike,

Thanks for the reply.

I know for sure this isn’t FreeSWITCH causing the issue, I get the CDR posted at the right time and durations are correct, it’s almost as if the far end PBX hasn’t noticed the hang-up, even though the BYE does get sent.

My carrier mentioned today (following a full trace from their end) that the PBX isn’t sending an ACK to the BYE, does that make any sense given the issue I am seeing? My main issue here is if it’s a PBX configuration issue, I am unable to look at and diagnose myself, so some sort of starting point would be really helpful .

I have never seen an issue like this, a pcap might tell you more, but i seriously doubt we are still sending media after the call hangs up.  I would suggest taking a look at a pcap and the debug logs and seeing that the call is actually being hung up on the leg facing the pbx and we really stop sending media.

  I’m experiencing a strange issue calling a destination within the UK, whereby media seems to still be connected after hang up.

  I only know this as the destination is a PBX, supplied by Unify (formerly Siemens), and that PBX on occasions records a voicemail, when a message is taken and after the call is hung up, there is a continuous tone heard on the end of the recording. The call logs show the right duration and the carrier has also confirmed that the call ended as the logs suggest.

  So, I’m wondering if anyone else has come across the same sort of issue using FreeSWITCH? The end user has told me they never used to experience this issue using a different provider, and I can’t reproduce this issue at all using other types of PBX, all calls end as they should and voicemail recordings end when the call does.

  This issue doesn’t seem to be a FreeSWITCH one, just thought it worth an ask to the group.
