The U.S. Department of Justice says Alltel
, a telecommunications company with 12 million customers, must not receive an extension to make its "push to talk" service compatible with wiretaps. In a letter
to the Federal Communications Commission last month, the department said it "opposes the granting of any further extensions" to Alltel, which had wanted the requirements to be delayed until Jan. 30, 2006.
On Aug. 4, the FCC ruled that push-to-talk services on cell phones, which resemble walkie-talkies, are subject to the Communications Assistance for Law Enforcement Act, or CALEA. The Justice Department also has objected to extensions for AT&T Wireless and Sprint.
