    There are too many variables with DTMF problems to provide a short answer to this question.It might be caused bya poor internet connection or that the provider is not fully supportingDTMF recognition protocols. This used to be a common problem with various providers implementing different standards. You can turn off Out of Band DTMF by going to Extension Management and on the far right side click on the codecs for the given extn. You will see an option for the OOB DTMF. Also, try using a different preferred codec (the top most codec in the list). If you are using an IP phone there might be some additional things to consider. You may need to open a support request to investigate futher.
