Remote J179 (ASBCE - TLS) Calls not Disconnecting right away "Number Busy"

[dsm600rr]

Hello all,

So I have a remote J179 via an ASBCE using TLS. During testing, everything is working 100%, aside from an issue with called party (my cell) hanging up first.

If I make a call from the J179 to my cell phone, and hang up from the J179, the call disconnects right away, as it should on both the J179 and my Cell Phone.

Now, If I hang up from my cell phone first, the J179 displays "Number Busy" along with a consistent audio tone for about 20 seconds and then it finally disconnects.

This is what SSA Shows once the call has been hung up by my cell phone:

Here is a tracesbc from when I hang up the call from my cell:

From the Initial Hangup:

Once it actually disconnects 20 seconds later:

The ASBCE is behind their Firewall, which is doing 1-to-1 NAT per their Admin.

Thoughts?

What is the content of the SIP INFO message?

I don’t see any BYE message.

You should see a BYE message from your provider to the IPO (in SysMon) and then from IPO through SBC to the J179

IP Office remote service
IP Office certificate check
CLI based call blocking
SCN fallback over PSTN

First shows when I hung up the J179

Second trace is when the J179 finally disconnected after showing "Number Busy" along with a consistent audio tone for about 20 seconds.

Not seeing a "Bye" anywhere in a Monitor Trace - other than "Allow: INVITE,ACK,BYE,CANCEL,SUBSCRIBE,NOTIFY,MESSAGE,REFER,INFO,PUBLISH,UPDATE"

I also am not seeing a "Bye" when I hang up from the Remote J179 and the call disconnects correctly.

Looks like this was a know issue with the client and the carrier not sending a disconnect clear.
