Error

I have Drupal 4.7 installed, then I download Asterisk integration package from http://drupal.org/node/31142/, install it as written in INSTALL.txt. But when I open my information page ( http://192.168.0.13/drupal/?q=user/1/edit ) I get an error
Fatal error: Call to undefined function: form_textfield() in /usr/local/apache/htdocs/drupal/modules/asterisk/asterisk.module on line 762

Also, when I press "my calls" link ( http://192.168.0.13/drupal/?q=user/1/calls ) I get an error
Fatal error: Call to undefined function: tablesort_pager() in /usr/local/apache/htdocs/drupal/modules/asterisk/asterisk.module on line 1070

Also at administration section there is a big error message:

,
though I created the neccessary tables for Asterisk in Drupal database as it was written in installation manual... =(

What could be done with it?
