I see it's your first post here, so welcome to the community! Changing your HughesNet plan will not improve performance, it is the same regardless of plan. We certainly would like to help your VOIP quality concerns, so I pulled up your account and ran diagnostics on your site. This is to ensure the internet service supporting your VOIP service is working normally, and all looks great on that front.
To help us investigate further, please privately message me with recent phone numbers, dates, and times when you experienced garbled audio. Recent incidents will help our engineers the most, so they can go back and review the relevant data.
Your cooperation, patience, and understanding are much appreciated.
We're closing this thread since we never got a reply from you. If you still have concerns, please start a new thread and include a detailed explanation so we can more effectively help you.
