Someone approached me because their system was have periods of intermittent poor call quality and the usage graph on the dashboard was showing phones constantly going offline.
This is an on site FreePBX 14 from distro. Using Sangoma phones (S300, S400, S500, DB20).
Everything was up to date when I logged in for the first time.
I switched them from Asterisk 13.22 to 16.3, but otherwise made no major updates.
As I stated watching things, I noticed that there are 10’s of thousands of NOTIFY packets spewing from the PBX in a 20 minute period.
The only thing I had turned off in the filter was notfify. You can see that there are only 835 messages outside of the notify.
Ext 20 is a S500
Ext 64 is a DECT DB20
EPM shows firmware 1.54 in use
Has anyone seen this before? This seems like an excessive amount of notifications and I am wondering if it is impacting the phones.
