Grandstream GXW-4104 provisioning problem.

[Maryan Petryshyn]

Hello.

After 3.5 years of excellent work gateway Grandstream GXW-4104 stopped authenticating on my 3CX. Firmware version is 1.4.1.5 (Program : 1.4.1.5, Loader : 1.1.3.4, Boot : 1.1.3.2). I could not restore the backup config and after that, I reset the gateway to factory settings.

I use instructions on how to configure Grandstream GXW-4104 in 3CX with provisioning (https://www.3cx.com/voip-gateways/grandstream-fxo/), but the gateway cant download the config file with error:

FW_UPGRADE: ERROR 403 GET /provisioning/xxxxxxxxxxx/cfg000000000000

Provisioning link is OK because I downloading file from my browser without any problems.

Before I reset the gateway error message was:

No SIP Account UserID to start registeration
m_api.c 1311 Sig chan already reset to default : 15 val

Have you any ideas on how to fix it?

Thanks.

3CX v18.0 Update 3 (Build 461)
Server: Debian
Hosted on Intel NUC locally.
Provisioning method: via LAN
SIP Provider: 4xFXO gateway
The firewall check is all green.

Hi,

If you can, try to reflash the firmware. But make 100% sure that you only download the firmware from the official Grandstream site!

You can also try to delete the Gateway from 3CX SIP Trunks, and recreate it to make sure you get a fresh config.

Make sure please that the NUC and FXO are both on the same network and subnet.

I tried to reflash but my firmware is the same as downloaded from the site:

FW_UPGRADE: Abort, Same as stored GET gxw4100b.bin

All other your advices I did before. Thanks.
