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.<br>
<br>
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.<br>

<div>Hi,</div>
<div> </div>
<div>I’m experiencing a strange issue calling a destination
within the UK, whereby media seems to still be connected
after hang up.</div>
<div> </div>
<div>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.</div>
<div> </div>
<div>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.</div>
<div> </div>
<div>This issue doesn’t seem to be a FreeSWITCH one, just
thought it worth an ask to the group.</div>
<div> </div>
<div>Cheers,</div>
