Thanks for creating a report! The issue has entered the triage process. That means the issue will wait in this status until a Bug Marshal has an opportunity to review the issue. Once the issue has been reviewed you will receive comments regarding the next steps towards resolution.

A good first step is for you to review the [Asterisk Issue Guidelines|https://wiki.asterisk.org/wiki/display/AST/Asterisk+Issue+Guidelines] if you haven't already. The guidelines detail what is expected from an Asterisk issue report.

Then, if you are submitting a patch, please review the [Patch Contribution Process|https://wiki.asterisk.org/wiki/display/AST/Patch+Contribution+Process].

Please note that once your issue enters an open state it has been accepted. As Asterisk is an open source project there is no guarantee or timeframe on when your issue will be looked into. If you need expedient resolution you will need to find and pay a suitable developer. Asking for an update on your issue will not yield any progress on it and will not result in a response. All updates are posted to the issue when they occur.

Please attach a log of the AMI interaction showing the AMI action executed, the complete response, as well as the output of "core show channels" and "pjsip show endpoints".

maybe the problem is in "res/res_pjsip/pjsip_configuration.c" file
in "active_channels_to_str" function
.... from....
if (endpoint_snapshot) {
return;
}
.............
....to .....
if (!endpoint_snapshot) {
return;

Oh, you're using the XML HTTP Manager interface. That is seldom used. If you use the normal AMI mechanism on port 5038 does it work as described? It may be an issue relating to the XML HTTP functionality.

the behavior is the same:

action:pjsipshowendpoints

EventList: start
Message: A listing of Endpoints follows, presented as EndpointList events

Event: EndpointList

Yes, that does seem to be the issue at first glance. Are you able to provide a patch on Gerrit to resolve the issue?
By: PeppeP (Peppe) 2020-06-29 09:27:50.066-0500

I can try, but I see that this problem is present in all asterisk releases from 16.3 to current relase. I don't check older releases but I suppose is not a regression.
So... one patch for each release... no sounds good.

By: Joshua C. Colp (jcolp) 2020-06-29 09:31:58.046-0500

Previous releases are not fixed. The change goes up to the relevant branch - so 16 and 17 for example. The fix will then appear in the next releases.

I'm waiting for "Contributor License Agreement" approvement.
By: Joshua C. Colp (jcolp) 2020-06-30 04:00:28.934-0500

Putting back into feedback until license agreement is accepted. Commenting will automatically place this back into triage.

Digium has refused my subscription.
I'll make it right.
