EXP module for the T27P and T29G

[_alx_]

Hello,

I would like to ask if there is an EXP module that fits with the T27P and T29G units.

The exp38 and exp39 cannot be mounted on the phones because the holes are wrong.

Will yealink put out a new exp module?
Also these two units do support the exp38/exp39 or not?
Last time I checked the T29G unit needed a beta firmware to support the exp modules.

There is an EXP20 that works with the T29G. The one thing I don't like about it though is the backlight timeout settings don't follow the phone. It's backlight stays at the same level all the time.
