BP50/250 DTMF from digital phones

If we have a door entry unit attached to an analogue extension port on an ELUA card.
If it is in use and the door calls and is answered by a digital extension, say a Dialog 4223...This user then
presses 8 on the keypad to open the door.
Question is - will it work?
Does the digital extension send dtmf tone back correctly when keying 8, or any other number.
I know that an analogue extension will do this.

Yes, it will...activate on analogue extension (connected to the door phone) cmd 0121 - DTMF to instrument
