Ofcom is waiting to see what the forthcoming amendments to the European Universal Services Directive look like before deciding what to do about VoIP location information. There has been some pressure to make VoIP providers provide the ability to record location information based on the IP address of the caller.
This, whilst technically doable, is very complex and likely to be hugely expensive. What’s more most VoIP providers are not ISPs and therefore do not have access to an ISP’s core network and customer database to be able to facilitate this. Those ISPs providing services to customers wanting to run VoIP therefore have no incentive to spend the cash.
More on this in due course but probably not until towards the end of the year.
