Hi

Unity Connection version 7.0(1)

The DTMF-id for all the users is set to the last 4 digits of the DDI (which is the same as the DN configuration of the IP Phones).

I've set up a Forwarded Routing rule to forward callers directly to the sign-in conversation when they dial 5775 internally or +441753485775 over the PSTN

This works for internal calls. Hence when a user dials 5775, they hear the prompt 'Enter your ID followed by #' . After the user enters the DTMF-id, the user hears the prompt 'Enter your PIN followed by #. This proves that the Forwarded Routing rule has been configured correctly.

The does NOT work for external calls. When user dials +441753485775 from an external phone (eg cell phone/mobile phone), they hear the prompt 'Enter your ID followed by #' . After the user enters the DTMF-id, the user hears the prompt 'I did not hear your entry'.

Has anybody come across this before? How was the problem fixed?
