I have a friend who has a business in Wellington CBD. Currently his landline and Internet is with Spark. His landlines appear to be a simple PBX though I am not sure and Internet is xDSL.
He is looking at DDI (extensions) and VoIP seems to be the way to go. He could move ISP's since I can't see anywhere on the Spark site where they offer VoIP, only some sort of Centrex service over ISDN. (correct me my research is wrong here)
Anybody have any familiarity with Vodafone VoIP service in the Wellington CBD or perhaps should I just get fibre to the office and go with a VoIP provider?
