Paging and intercom

Good day friends!
I have such a problem can you help…
FreePBX 15 is installed…
There is a task to play one audio file every day at 9 o’clock.
For this I use a paging intercom module
The problem is that there are two devices Grandstream and Huawei eSpace 7910
On Grandstreams the process works as it should when calling a special intercom group number one beep and the handset is automatically picked up and played
But Huawei eSpace 7910 rings two beeps but does not automatically pick up and rejects …

What have you done to the Huawei to disable the protection against eavesdropping? Autoanswer is not something that should be possible to invoke in the default set up for the phone.

If you have enabled it in the phone, you will need to provide SIP protocol logs.
