Both Digital Voice and the hybrid connect rely on the SH2 and will not work with a third party router.
If you wish to use the Asus in conjunction with the SH2 in order to avail yourself of DV and hybrid connect, you will need to configure the Asus as a secondary router

Thanks for info.I guess that is an option if it is not too complicated a procedure. Would mean i could still use the digiIal landline and avail of the hybrid connect..I surprised myself getting the Asus router working so quickly this morning. I will check out your link now.Thanks again.
