EPM Phone doesn`t go to default template

When one user make logout from Digium D50(fw 1_4_2_1_73372) another user can not login to his account.
Then make a login on a display on D50 “Request falied. Please try again”.
Phone after logout doesn`t go to default template. And in config file MAC.cfg in the bottom i find string without IP adress PBX.
