greetings all I have been having intermittant issues with various flavors of ATA not keeping their registrations over extended periods of time. This has happened with both Sipura and Grnadstream ATA. They all install and operate correctly for at least a week or so. Then I notice screenfuls of registration failed messages on the * console. Doing anything to cause an ata reboot corrects the problem - for awhile. But it always comes back again. I have some units - both brands - that work fine . Hard to predict which units will act up. They are all running the same software and are configured the same. I did change timers so they will retry to register quickly and that solved one issue. My problem now is they fail registration. Any clues/suggestions appreciated. presently waiting for one to act up so I can capture a sip debug.
