GRP2612Ps Won't stop ringing until all are rebooted

[healthy]

I'm having an issue where an office with Grandstream GRP2612Ps have been spotty. They sometimes don't behave as expected, and will also ring without stopping until the IP phones are rebooted.

We have had this issue over the past 7-8 weeks and have had to reboot the phones at least once a week.

Most phones are on firmware 1.0.5.93, but the last 3 we purchased are on 1.0.7.2 which says unsupported (they came with that firmware). Of the 12 phones, the ones on the later firmware are less of a problem, and the ringing issue predates them.

When the phones are ringing, we don't see any activity in the dashboard.

Any help is most appreciated

Hi,

1. Are these STUN phones?

2. What does it show on the screen during ringing?

3. What version is your PBX?

4. Are you using modified templates?

Hi JohnS
1. They are local LAN Provisioned, Server is STUN and Dynamic IP
2. I don't know exactly what hte screens are saying during this. We get calls reactively, will ask next time.
3. PBX is v.18.0 (Build 461)
4. No modified templates.

I'm being told that it looks like a call comes in and bounces around the system, but they cannot pick it up, and that appears to be what triggers this constant ringing.
Thanks,
Scott

Hi Scott,

If you login to the 3CX apps (Desktop / Mobile / Web) do they also get these calls?

Server is STUN

I didn't understand what this means - STUN and LAN provisioned are two different things.
Kindly read the below article and provide us with detailed information so we can better understand how your system is deployed.

The Phones are LAN Provisioned, I don't have any users that use the mobile app, so I haven't been able to check that. I will make an extension with the mobile app setup, but it would necessarily be off the local LAN, not sure if that will be a worthwhile test.

Hi Scott,

The new firmware has been released, v1.0.7.33 which fixes a known issue where the ringer randomly stops working.

You can find the update in your management console.
