回复:网络电话:成功设置免费拨打1800等toll-free电话
My line 1 uses VD and line 2 uses sipgate. With sipgate 800 # is free. So in my case I uses line 2 to dial 800 numbers.
In spa1001 phone tab, "line2 select code" is #, so when I dial 800 numbers I dial "#1800xxxxxxx". Tested and my VD does have the record and sipgate has it.
