Longer DTMF Tone for call bridges T26P

[markus.pfirrmann]

Hi - we are using a phone Bridge where you have to enter the Conference lines and Passwords by DTMF - quite common I think.

Now it seems that the "Beep" is too short since we do get lot's of Errors where the "beep" (= Number) is not recognized or not correctly recognized.

Is there a way to extend the Duration of the DTMF "beep"?

We are using the T26P phones.
