How many MXSDs can I define in LD 86? The NTP just shows XXX as the answer. also, I have my T1 as the first choice on all my area codes with no DMI. My second choice is copper, with a DMI of 1, which deletes nothing and inserts a 9. If my users already dial 9 to get out, how in the world does a call complete over their copper (2nd choice) if the T1 is down? won't their call go out as 99+1+area code+tel #?
