If you don't have a loop key on the digital phones and what would normally be line 6 key is also something else then when you dial 9 the system can't give you line 6 so you get the next one. SLTs don't work quite the same way, they always get the last line in the first line group which in your case is line 6 or higher. You need to remove all lines after 5 from co trunk group 1 and that should fix the problem.
