Disa hangs incoming connections?

Weird things happen to me so that other people are spared the frustration

Background info
FreePBX 2.11.0.37
Asterisk 11.7.0
I have two phones in my home office:
an AT&T POTS line and an internet phone.

The problem
I set up a DISA “123” on the main IVR.
I call the PBX from my internet phone and dial “123” I get the DISA prompt, put in the PIN and get a dial tone. I then dial 9+1+{phone number of my POTS} the pots phone on my desk rings. I answer and have a talk with myself and hang up both phones.

Now, when I use the Internet phone to dial the PBX, I get a recording saying that the {phone number of my Internet Phone} is not in service!! Logs show this recording is coming from the SIP provider to the PBX. (not the phone number I CALLED from my Internet phone - but my OWN number)

So, for giggles, I use my POTS phone to call the PBX/DISA and dial 9+1+{phone number of my internet phone}. It rings, I answer, I talk to myself and hang up both phones.

When I try AGAIN (calling from my internet phone to my POTS phone) I get a recording saying that {internet phone number} is not in service.

BOTH my phones (pots and internet) can call each other directly, either can call any OTHER number … but when either is used to call the PBX, the log file shows that Integra Telecom is playing the “not in service” message and then playing the phone number I’m ON.

This condition lasts for about a half an hour during which time
– neither of my phones can dial the main PBX
– the main PBX is taking calls just fine for everyone else
– my phones can dial other numbers just fine

It’s as if the call chain never fully collapsed and Asterisk is waiting for a reconnect?

Here is a snippet of the log file (310328xxxx) is my POTS line number
