Depends on the CP (communication provider), they are all sorting out what to offer.Our phone is part of our broadband package and has been for about 17 years so I'm assuming we won't notice any changes.
Some may opt to just provide a connection for broadband and not get involved with the complexities of VOIP forcing those who require a landline to use a third party provider and maybe an ATA.
Why support a market a market which is dying due to mobile use?
