CBS: " Former president Barack Obama has denied President Trump's claims that the Obama administration wiretapped phones..."
Independent: "The FBI disputing Donald Trump's claim Barack Obama had his telephones tapped..."
AP: "President Donald Trump on Saturday accused former President Barack Obama of tapping his telephones..."
The FISA warrant apparently targeted a server, so it would be surprising if they tapped a telephone to find out what the server was saying to another server. I'm going to guess that the Obama team's careful denials, parroted by all these media outlets, mean that no actual telephones were "tapped." So we're only talking about internet traffic, servers being penetrated and covertly examined, maybe reading emails... but no, absolutely no "telephones."
The right thing to do would be to come clean on what spying was done, but of course they can't: all the information is surely classified at a high level. Still, some sunlight and honesty -- and not these carefully construed denials -- is the only way to restore any sort of trust.
