Hi, 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. Cheers, Stuart
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.

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 .

Your carrier is an idiot. You don't ACK a BYE. Do they mean you are not getting any response from the BYE? Double check the sip trace that all the IP's are right and you are sending the BYE to the right place. On Aug 20, 2014, at 2:17 PM, Stuart Mills <stuart.mills3@btopenworld.com> wrote:

I did think it was a bit strange, I’d never heard of it before today (now I know why). Maybe it’s the relay of information to me that’s at fault here, I’ll double check that.

Is there any NAT in place? BYE goes to the Contact address, which can be incorrect. On 20 August 2014 21:25, Stuart Mills <stuart.mills3@btopenworld.com> wrote:

Stuart, Years ago when I ran an exchange with analogue trunks I used to experience this problem. I cannot remember if it was down to the BT exchange or my exchange, but it was related to line polarity reversal on connect/disconnect. The continuous tone is provided by the (BT) exchange to indicate that the call has cleared and the handset needs to be replaced. In any case, if your CDR agrees with your carrier's CDR, then the problem is between the remote PBX and their service provider. It would be interesting to see what happens if you made a direct SIP call (ie from a client, not freeswitch) using your service provider to that PBX, and using another (perhaps free, trial account) SIP provider to that PBX. Comparing results should help to identify where the problem might lie. John On 20/08/14 01:19, Stuart Mills wrote:
