How to recognize a phone number using xml grammar?

Question

I’m using nuance to recognize voice in calls,

I need to pick up the person’s phone to validate the registration, how to do?

For example, if the person says 95 (ninety-five) - I’m getting 90 - 5 and not 95.

Follows grammar of test:

NOTE: I put as if it were javascript but it is an xml file.
