Yealink and dialing a number from 3CXPhone

[jasonhayes]

Hi When we use 3CXPhone to start a call, say from the phonebook, on the Yealink phones it passes the call to the T24 phone and sounds DTMF tones via the speaker, is there anyway within the provisioning file to disable this. Happy for the call to be connected and hear the ringing tone via the speaker, just not the number being dialled.
