yes, there seems to be a problem with MSN last night. I think it is cleared up now.
As for your question, typically you would see digit received for each one. I cannot say why you are not seeing this for all the digits. Additionally, when you use the test o command, you do not need to put a v at the end.
For RNIS, I am sorry to say that I do not know what that means. If you could give me the description, I could tell you whether it is supported.
