I am working on a legend v6. Presently the system has loop start lines and some lines on a T-1. Everything is moving to the T-1. The first 15 channels of the T will be GS trunks. 16 is open. 17-24 are DID/DOD. Can the DID/DOD lines be used for outbound traffic? For DID to work I have to change the DID/DOD channels to rotary.

T-1 changeover

Best advice is to order all 24 channels as 2 way e&m trunks with DID's. This gives you 24 dynamic channels for in and out use as well as DID capability. Then any inbound number that rides on the T-1 will have an associated DNIS number that will match an extension on your switch. Tyipcally, on a Legend, 3-digit DNIS are fine. Make sure there are no conflicts in the DNIS such as 0, 9, 9 or 7 for a default dial plan. You don't set the channels to "rotary". This is done if you are getting DID's on analog DID trunks that interface via a DID card on the Legend.

The T-1 is already provisioned. So I don't have any leeway there. I have 15 phone numbers on the first 15 channels. 17 through 24 are for the DID/DOD. So I should be able to use the DID/DOD for outbound traffic, right? My extension number range is 100-160. My DID range is 7700-7799. Where can I program the DNIS translation? I don't know if I should delete the 7 and change the extension number range to the 700s or what.
DID= Direct Inward Dial
DOD= Direct Outward Dial
You need to program the DID's under LINES/TRUNKS > DID.
If your provider says you are rotory, then you have to provision the trunks as rotory.
From the information you supplied, you are going to have a conflict- 770-791 are the default numbers for calling groups. You need to know how many digits your provider will be sending. If they are sending 4, and you delete 1 then you will have a conflict with 70 (the main pool). If they are sending 4 and you delete 1 and then insert 4, this gives you an extension range of 4700 thru 4799, inserting 3 gives 3700 thru 3799, etc. If they are sending 3 digits (which are always the last 3 or 700-799) you would delete 1 and insert 4 for an extension range of 400-499 and so on. It boils down to how many digits they are sending and how many you are using and the ranges you are using.
