Cisco 7821 cant enter meeting PIN, tries to dial out instead

[_Mark_]

Hi team,

I have a Cisco 7821 configured as a meeting / conference phone, when a user tries to enter the meeting PIN the phone tries to dial out instead of accepting the PIN, I'm not sure what particular configuration setting could cause this, any help would be greatly appreciated.

Hello Mark,

please can you provide more details about the platform you are using, for example is it CUCM or CME, and the connectivity you have with your provider?

It looks like you cannot send correct DTMF tones.

Hi George, thanks for your reply, it is CUCM and I'm not sure about the connectivity. The issue is confined to one particular phone, our other conference phones can all enter the PIN without issue, it is just one particular EXT. I compared the individual configuration of a phone that can do it and the one that cant and they seem identical except that they are different models.

Hello Mark,

Have you tried to check on the phone device settings on the CUCM Admin Page under Protocol Specific Information "Require DTMF Reception" ?
