PBXAct17:
Recently noticed an issue where Parking Space keys (DSS Keys) on P370 phones no longer work, the call is just dropped, and the outside party hears “I’m sorry, there is no call parked on that extension”
The predefined “Park” button in the call processing section at the top of the screen works, but even using that method, the outside party hears the recording that the internal user is supposed to hear “7001”.
When I first noticed the issue, I checked and there were a number of available module updates that I applied. This did not resolve the issue.
I was paying close attention to previous versions as opposed to newer versions of the modules I updated. I referred back to those notes and provide the notes related to the two parking module updates here, as it seemed most likely to be related to these modules.
Those modules were:
Previous Version Update Version
Parking Pro 17.0.1.6 17.0.1.7
Parking Lot 17.0.2.7 17.0.2.9
After those updates failed to resolve the issues, I began searching and found an article stating the information:
_____________________________________________________________________________
"Both of these symptoms point directly to an issue introduced in recent updates to the FreePBX/PBXact 17 Parking Module (v17.0.2.7+) running alongside Asterisk 20/21, which fundamentally altered how PJSIP blind transfers interact with direct-slot parking. [1]
When your Sangoma P370 phones invoke the predefined “Park” button or press a DSS key assigned to a specific parking slot, they send a PJSIP Blind Transfer. Due to the recent regression, Asterisk treats this blind transfer poorly, executing the announcement to the outside caller channel instead of the internal device, and completely dropping/disconnecting calls targeted at explicit DSS slot extensions. [1, 2]
How to Fix It
1. The Immediate Remediation (Rollback Core/Parking Module)
Because this behavior stems from a recent upstream module regression, rolling back to a stable module version immediately restores the old operational dialplan logic. [1]
Log into your PBXact SSH terminal and execute the following commands to rollback the Core/Parking modules to stable baselines: [1]
bash
fwconsole ma downloadinstall core --version 17.0.18.49
fwconsole ma downloadinstall parking --version 17.0.2.5
fwconsole reload

I tried this after first trying the updates mentioned above, and it also did not resolve the issue. And now, the Parking Pro moduleis currently at 17.0.1.6, and the issues remain.
