Huawei 8546m Voice Profile gets reset after device restart

Hello, friend!

In the first place, HG8546M is a customized product.

The cause of the problem you described: HG8546M delivers the configuration to the device through the OLT or ACS of the ISP.

When the HG8546M restarts, the HG8546M needs to resend the registration request, and then the OLT or ACS delivers the configuration to the HG8546M, therefore, the status displayed after the device restarts is Registering and the server address is incorrect.

The SIP server domain name (cg.ftth.ims.bsnl.in) is configured on the ONT web page. To put it more simply, this configuration is created on the HG8546M. When the domain name is created, the corresponding voice service is usually bound to the domain name. However, the voice service is created on the OLT. Therefore, the ONT is first restored to the configuration on the ONT each time the ONT is restarted, then, restore the ONT configuration issued by the OLT. After the device is restarted, the configurations issued by the OLT to the device are not restored. As a result, the configurations created on the ONT are invalid and discarded.

Solution:

As the product is customized for the ISP, you can contact the ISP to migrate the configuration delivered by the OLT to the ONT web page and then create the corresponding SIP server domain name.

Thanks!

Hello!

Your device is a customized device provided by the carriers. Some functions are restricted. For example, the modification of access control is fixed by the providers before they give it to you. The solution is to contact the carrier, ask them to initialize the device on the remote OLT (back up the data before initializing the device) and apply for unlocking all the locked devices.

Dear friends, you want to link to the Internet, but to achieve absolute security, this is not possible, we can only reduce security risks as much as possible.
