Help with uncovering the DNIS on T1 Help with uncovering the DNIS on T1 3219168 (MIS) (OP) 16 May 02 18:04 We have a 800 number riding on a T1 trunk group, we did not know what DNIS it's associated with. Is there a way to find it out other than to go to Phone company? We have none of the VDN's set up yet. RE: Help with uncovering the DNIS on T1 Phoneman2 (MIS) 16 May 02 18:29 Your fastest way would be call your LD provider/sales rep. Ask for a Customer service report for that 800 number.

Then dial the 800 number and watch the call arriving (advisable to pick a quiet time of day).
