For incoming FXO calls auto attendant does not respond to digit entry

[Halsser]

Hi All,

For incoming FXO calls auto attendant does not respond to digit entry from certain provider, whereas recognize digit entries from other providers normally and the forwarded the entered extension normally.

Call flow:

PSTN caller – FXO – (Router to CUCM sip trunk)-CUCM-(CUCM to CUC sip Trunk)-Unity

What the problem looks like Is it dtmf issue with this certain provider, or misconfiguration please help me how to fix this issue.

Just to clarify: are you saying DTMF isn’t recognized for any call on the analog line plugged into that FXO port or only calls originating from a specific carrier?

[Halsser]

Thank you for your response.

DTMF isn’t recognized for Only calls originating from a specific carrier.
