Hello,
at the moment we have some new problems with our FreePBX 17 system. Most times now when you make an internalt call you can’t hear the Ringback it’s silence until someone on the other side pick up. I’ve made some tests with the Follow Me module and set a “Hold on Music” this is most times hearable. That problem is very strange.
Sometimes when i call back with the other telephone you can hear it and then the first telephone is also working until you save some changes. I’ve tested and debugged a lot but i can’t find a schema that can cause this error.
I’ve enabled the debugger and the first line when the call starts is:
RTP Packet Debugging Enabled

Is it possible that this causes the problems? We don’t have high load we have only some telephones and 2 oder 3 calls in parallel.
Perhaps someone had this problem and knows a solution. We use a Vodafone SIP-Trunk and the Inband Progress is off (But that should not be relevant for internal calls).
At the moment i have enabled the Follow me on all phones and uploaded a Hold Down Music with the Ring tone and set that. This resolved the problem at the moment.
It is possible that this problem is caused by the Yealink DECT System that had problems in the past perhaps that doesn’t fetch the ring request.
I hope someone has an idea.
Linking this to your (reposted?) other issue … it is interesting that you were able to trigger the task processor queue limit in this way.
That error comes very often. When i check the processor it’s not full or near the limit. Thats the interesting thing.

What version of Asterisk? What is the output of “core show taskprocessors”? Is there a log to show the call that doesn’t send ringing? What is the SIP signaling?
This problem is mostly on internal calls here i can reproduce it. But i think this could be a problem from the Yealink DECT system that doens’t sind a Ring but i can try to debug this next Wednesday when i’m at the office. I use the latest FreePBX 17 Version with alle updates.
The interesting thing is that it’s working when i change in the follow me module the “Ring” to a sound then it’s working. Perhaps the SIP Ring is not send or not taken by the Yealink DECT phones. That system seems in general a but buggy. But i try to debug it.
Sometimes i got the problem with the ring also from outside but mostly on internal calls.
Here is the output from the Task command:

FreePBX is the GUI, while Asterisk runs underneath. Their versioning is decoupled. The version of Asterisk can be determined using “core show version”. I also anticipate the stasis pool control is due to manager usage in some capacity. On a FreePBX system with current configuration those don’t actually impact anything directly.
Yes i know but i use apt to update it so it’s the last version from the repository. But i can check all that poblems again next week. Perhaps there was an update and something is fixed now.
Version is
freepbx*CLI> core show version
Asterisk 21.9.1 built by jenkins @ 5f98a1fe2d02 on a x86_64 running Linux on 2025-05-27 06:58:42 UTC

There are multiple current versions of Asterisk - 20, 21, 22 and in FreePBX you can switch between each. It’s why being explicit with the version number is important, as latest can mean different things.
I’ve made update there was an update from Asterisk 21. Now it’s
Asterisk 21.10.0 built by jenkins @ 210f6a7da950 on a x86_64 running Linux on 2025-07-21 09:14:47 UTC
On both systems. Is it a good idea to switch to Asterisk 22? Is it supported by FreePBX? Is there an easy way to switch between them to test? Or do you think 21 is fine at the moment?
But thanks for your help.
I will make also a Ticket at Yealink to check if the DECT and SIP is working correctly or if they have a problem with the Ring.

I would not anticipate changing altering the taskprocessor messages, or altering the ring behavior.
Yes but the Limit is arround 500 i think and it’s only 222. This is what confuses me. And we have only maximum 5 to 6 parallel calls.
The interesting thing is. When i have that problem and i call From A to B … no ringtone. Then i call back from the other site. After that it’s working. But like i said. It’s possible that this is a problem with the Yealink DECT station we had there some other problems and got new firmware.

By the time you looked the queue could have very well gone down. The output you showed did indicate it went over, though, specifically it hit 3720.
Without a log for the ring issue itself, I can’t really say either way the cause. It could very well be the DECT station as you mention.
