I am unable to set any parameters for Multicast Listening via Web UI.
Going to Directory>Multicast IP, I am supposed to see:

But instead I have this:


Screenshot 1 is shown when you log in as an administrator, screenshot 2 is shown when you log in as a user.

Now that makes perfect sense.
Can you give me the admin creds?
Verizon did not know of any.

By default, the username/password for the admin is: admin/admin and for the user: user/user
But because the device is provided by Verizon, the admin password will be different, I think.
What you can try is to reset the device to factory settings. But keep in mind that all settings will be reset, including passwords.

I had previously tried admin/admin but I was met with an "incorrect password" message. I also tried admin/(last 4 digits of MAC) because I read that somewhere. That also did not work.

So now I tried your idea of the factory reset but unfortunately that did not help either. I am still getting "incorrect password" with admin/admin & admin/MAC.

Now prior to posting here I was speaking with Verizon and was told that they do not change any settings in the phones. They use them as-is "out of the box" but, clearly, there is something stopping me from accessing the admin login.

I will go and take this up with Verizon once again but if you have any other ideas I welcome them. I can't be the only one wanting to institute multicast paging on the T53W.

Thank you

Please try this:
Disconnect the phone from internet (not your network)
Factory reset the phone
Try to log in with admin/admin
If successful, the phone is likely provisioned by Verizon. This can be checked by restoring the internet connection so that the phone can be provisioned and thus the password change.

Kind regards,
