[iamnewborn]

Hello

i have the following dialplan:

dialplan.dialnow.rule.1 = 90[1-9]
dialplan.dialnow.line_id.1 = 1
dialplan.dialnow.rule.2 = 98[34589]xxxxxxxxx
dialplan.dialnow.line_id.2 = 1
dialplan.dialnow.rule.3 = [0-8]xxx
dialplan.dialnow.line_id.3 = 1
dialplan.dialnow.rule.4 = 9810xxxxxxxxxxx
dialplan.dialnow.line_id.4 = 1


dialing:

901 => OK
984445556677 => OK
0000 => OK
9810123456789 =-> FAIL, it begins to dial after "8" was entered.

Where there is a mistake?
