GXP1760Ws keep freezing

[AS19]

I recently noticed that about 5 out of 8 of my GXP1760Ws keep freezing with the more recent versions of 3CX.

Its always the same 5 phones.

When the phones freeze they drop off the network, they no longer respond to ARP or ICMP. The phones don't respond to pressing buttons on the phone it self. Rebooting the phones by pulling the power cord will get them to work for a few hours.

On Friday, downloaded the new GXP phone template 3cx update, then I went around the building and factory reset the affected phones. Updated the phones to the latest firmware and then re-provisioned the phones. A few hours later I started getting emails from my network monitoring system, all the phones I had reset all went off line in the order I had reset them over the course of an hour. All the phones are were still frozen when I came to work this morning.



GXP1760W firmware version: 1.0.1.98

Sounds a network issue. are the phones connected to a Poe switch - any errors on the switch, are you pulling too much power,

Have you tried another switch

if you factory default the phone, and do not apply 3cx config does it do the same ?

 

[AS19]

These are wireless phones, they are not on a POE switch. These phones are also connected to several different wireless access points and we have 3 GXP1760Ws that work that are connected to the same APs as the phones that freeze.

The phones are totally frozen, they don't respond to any input using the keypad on the phone, its not just ARP / ICMP that's not working.


I haven't tried resetting and leaving the phones un-provisioned yet

You could try an update to latest PBX release v16.0.4.504

 

[AS19]

Hmm, I'm only seeing an Alpha release as available.

Hmm, I'm only seeing an Alpha release as available.

I probably dont need to mention this but dont touch the Alpha release - these versions are for testing only and should not be used in a live environment.

@AS19

Get one of these phones on a wired network for troubleshooting and monitoring.

See if you can replicate the issue while wired. Do not use a wireless-to-LAN bridge, patch it in straight.

 

[AS19]

I hooked 2 of the phones that were freezing up to the wired network and factory reset and re-provsioned as wired phones. These 2 phones are still freezing.

There is some kind of timer until they freeze. My network monitor keeps reporting the phones drop offline with in minutes of each other after I fix them. Will have to time this to see exactly how long it takes

 

[AS19]

The phones constantly freeze after roughly 20 minutes

You said in first post you were in

3CX Version, Standard Annual 16.0.389

so it wasn't latest release, but if in update only Beta is available then you should be in latest release (can you confirm ) but not the 16.0.389

 

[Jesus Montoya]

I am having the exact same issue with 3 of my phones. I have the exact same firmware version and 3CX version as you. Maybe it is a firmware issue with the phone itself.

 

[JohnS_3CX]

Would it be possible to take a device home, and get a new free instance and test it at home?

You can connect it to the free 3CX instance as STUN using a LAN cable to connect it to your modem.

This test will show how it behaves in a different network environment (and on the latest PBX edition + latest firmware).

 

[Evolute IT]

Grandstream released a firmware last week that finally fixes the freezing problem when on Wi-Fi.

 

[AS19]

that new firmware did not fix this issue
