I have users complaining that when the dial out over PSTN to various far ends that require passcodes or prompts that the other end is not recognizing the DTMF. The call is able to be made fine and connects, but anytime the user has to do anything regarding entering a passcode etc.. it does not recognize and they cannot proceed. These users are using 9630 IP phones and calls going out over ISDN PRI circuits. Is this a carrier issue.. physical issue with the MM ??

Had this issue a few times. I opened a ticket with our carrier and it started working again. I would try routing the call through a different carrier via routing/ars and see if it works or not to determine if its a carrier issue.Comment
