Is it possible to reprogram the "Conf" key on a partner 18D or 34D telephone to be a "Recall" key instead of a "Conf" key.

No, the Conf a set key.

Kinda thought that since it had a "hard" button. Just needed confirmation. Thanks again.

Do you just need a Recall button on the set....or were you just wanting to use the programmed Conf button. You can program recall on an open button if that is what you are trying to do.
