Have you requested an informal conference with a senior reviewer about the Top Level Review option?
do not
Do you know what will be done if nobody answers the calls of the superior reviewer?
no, I don't know that information
What if I received a SOC or SSOC on the issue in your Notice of Disagreement?
You have 60 days or the remainder of the 1-year period after the decision you appealed, whichever is later, to opt for the modernized system by submitting one of the following forms and checking the SOC / SSOC checkbox:     Request for Decision Review: VA Supplemental Claim Form 20-0995
what can happen no one answers calls from the top reviewer?
in that case they will leave a voicemail.
And in the conversation that I will have with the judge, will my representative be able to participate?
of course if you have one this can help you in the audience.
What do I do If I request a Board Appeal and want to change to a different appeal option?
