Problem: When the application (Asterisk based) asks user to enter a phone number, some of the digits appear twice, it happens in about 70% of cases.
For example, if user entered a number: 9542322800 then the application will receive: 955423228000 or another combination where one digit or few is captured twice.
Answer: Please try to use Inbound or RFC2833 DTMF type at your endpoint to resolve the DTMF recognition issue.
Furthermore, you can try another carrier to see if this issue is related to your carrier.
If the problem was not solved please open a support ticket.
