Hi Steven,
These features that you are trying to access need to be supported by your ITSP. For instance with the *98 code, your provider would need to understand what you are asking for when you dial this code. If they support this functionality then there may be a configuration issue that we can help you with.
Feel free to contact us at 1-866-606-1866. We will be happy to help troubleshoot the issue further.
Thank you,
Jason
