Reports of potential political phone call misdeeds in Indiana are ringing off the hook.

Indiana Attorney General Steve Carter confirmed Wednesday he is investigating a handful of complaints about so-called "robo calling" of political messages.

Meanwhile, a spokesman for U.S. Sen. Barack Obama said the Democrat's Indiana office has heard gripes from region telemarketers refusing anti-Obama calling work.

Carter said his office is investigating consumer complaints of receiving unsolicited, automated calls pitching presidential candidates.

Indiana is one of a small group of states with a law banning the automated calls and does not allow exceptions for political messages, Carter said.

Of the seven complaints Carter can confirm he is reviewing, five concern calls promoting U.S. Sen. John McCain's campaign, with the remainder as pro-Obama.

Carter noted that the complaints have not yet been fully investigated. The complaints originated in areas including LaPorte, Evansville and Kokomo, he said.

In another alleged incident that Carter said he is not reviewing, a group of employees reportedly walked off their jobs last week in protest of inflammatory anti-Obama rhetoric.

Jonathan Swain, spokesman for Indiana's Obama for America camp, said his office received several complaints starting last week from workers at the Hobart office of Naperville, Ill.-based telemarketing firm, Americall Group.

Callers told Swain's office that roughly 30 to 40 people had left work one day after refusing to read anti-Obama scripts during calls.

Workers were told they could leave and opt out of reading the scripts but would forgo their pay for that day, Swain said.

A spokeswoman for the McCain-Palin campaign in Indiana dismissed the call center reports as not newsworthy.

Americall president and CEO George Kestler did not respond to several calls seeking comment Wednesday.
