The rising number of jobless Texans has generated more claims than the Texas Workforce Commission can handle.
The commission has added hundreds of workers and phone lines to call centers to deal with soaring unemployment claims, but officials acknowledge that they can't answer every call.
Claimants are urged to file for claims on the commission's Web site, www.twc.state.tx.us, which also has answers to commonly asked questions.
The percentage of claims filed online has risen from about 30 to 50.
The state's unemployment rate jumped to 7.1 percent in May, from a revised 6.6 percent in April.
