I currently have conventional PSTN landline and FTTC broadband with another provider. I have a separate VOIP account connected via an ATA, such that I make outgoing calls via VOIP and receive incoming calls via the PSTN., using the same handset; (the phone connection is in to the ATA, then out to the phoneline)
I am considering moving to Vodafone who offer broadband with a Digita Voice "landline".
If I simply transfer the phone connection that goes, from ATA to phoneline, to ATA to phone connector on Vodafone router, will I be able to operate as before?
