Two people (both on the North Shore in Auckland) have currently told me that no-one is picking up the landline at my house. But when they call (from their landline), there is a dial tone... but the phone here does not ring. (Also, they do not have VoIP or any of those fancy options..)

I am a Slingshot customer (as you can probably see the forum title). I do not have "call blocking" on, nor do I have "Reject anonymous calls" feature on. One person is on Vodafone, whereas the other person is on Telecom. They have both before been able to get through, but not anymore. Any suggestions please?

Other people are still getting through fine as of now.. I have called Slingshot Customer Care and they tried calling my landline from all the available networks in New Zealand and it works fine.. Not sure why my two people can't call through..

(P.S I have heard that some Telstra Clear customers have not been able to call some landlines successfully, but they are not Telstra Clear customers.)
