How to modify the VOICE SERVER TYPE in an ONT HG8245H by VAS profile

Hi friend.

The difference between the NGN server and the IMS server is whether to support the subscription function. The NGN server does not support the subscription function, but the IMS supports the subscription function.

In other words, you want to not support the subscription feature.

The VAS template does not contain the item for changing the server type. However, you can disable the subscription function by modifying SIP parameters.

Here's the procedure:

1. Open the General ONT VAS Profile.

2. Modify 4 = 0 to disable subscription as shown in the following figure:

I hope I can help you.
