Enhancement to T46G - Add page turn button

[Elaine_Yealink]

Dear,

Thanks for your kind suggestion. Much appreciated.
But with this design we will need to add two more hard keys which may not be acceptable for other users. In addition, on T46, we supports 27 programmable buttons originally and we can support to add 6 expansion modules and these can meet the requirements for most of users.

Regards
Elaine
