Firstly, sorry if this topic has been asked before, i've used to search function and unfortunately found nothing. Also, if posted in the wrong sub-section, mods please feel free to move to correct one.
So, the story is, I am seriously considering Vonage, or another VoiP provider, to provide a service in providing a second telephone line in my house, with a local area code to my landline, purely for my business reasons. I rang Vonage up today, and the man I spoke to said quite unsure-like, that the Cisco 7800 Series telephones, or even any Cisco based VoiP phone would not be compatible on either a UK Residential or Business plan. I thought it would be good to ask for a 2nd opinion from someone who knows about this topic on this forum. What do people think? If it is possible, how difficult is it with Vonage or another company to preference the phone to the VoiP system?
Thanks everyone for your time!
