SOLVED Calls do not hang up

[TurabG]

Hi,

I am still testing a brand new installation. Even if the FusionPBX client hangs up, the other party stays active, until they hang up too. There shouldn't be a NAT issue because the client and the providers successfully registers and inbound and outbound sound is good and calls do not drop after 30 seconds. I tested that calls work for 5 minutes without a problem of connection or sound. Only this hang up issue. The other party is never disconnected.

I have seen several threads and Github issues from even year 2019 to this date, but no viable solution I could find.

Post some logs

Sorry for the very noob question: Which logs you mean? From freeswitch log which can be seen through Fusion admin panel or sngrep captures? And at which format suits best?

By the way I just noticed that outbound and inbound behaves differently:

Inbound calls: Sound is perfect on both sides. When the Fusion side (Leg A?) hangs up, the callers stays online until they hang up too. Never completes the call.
Outbound calls: No sound on either sides. When Fusion side hangs up, the other side stays up for about 10-15 seconds and drops the call.

I am not sure if this behavioral difference is newly introduced. I remember both were same before.

sngrep for now

Now I clean installed for production. I have now lost the sound too. I am adding the log screenshots here.

When an extension calls another extension, two calls appear in the active calls which of course show up as two entries in sngrep watch.

I don't receive neither dialing tone at the caller side, nor sound at any of the sides. No matter who hangs up, the other party stays on call, it doesn't automatically hang up. And even after the other party hangs up manually, the two calls stay active on the server forever.

I can call the same extension again and new double calls keep showing up in active calls. Now I have a dozen of active calls from the same caller to the same callee.

It is only after I manually hang up from the control panel -> active calls I see a BYE message in sngrep and the response says call can not be found.

This has been solved. I have been testing Fusion on a local instance and since both phones and the server were local, I hadn't needed RTP ports to be configured in NAT. But now my candidate production instance is on a VPS and behind a firewall. I forwarded the RTP ports and hang up issue resolved.
