According to Dr. Steven Greer, yes, SETI has received multiple extraterrestrial signals. This news he says, is confirmed by senior employees within the SETI program.
This is what Greer had to say at a recent Exopolitics Conference:
"We have confirmation - and I'm not going to give the name yet because we are trying to coax this guy out of the closet - but one of the senior people in the SETI project, which is the Carl Sagan Search for Extraterrestrial project, has confirmed to the Disclosure Project that they have received multiple extraterrestrial signals," Greer said.
"but that now they are getting external human, probably NRO or NSA jamming of those signals and they are getting very frustrated."
