I want to be able to set up IP phones so they can receive phones from off of campus. I was told I needed to set up a DID.
We have a Definity G3si Switch. Currently we can make calls to off campus numbers.
Can any one offer any assistance in how to do this?
If you are trying to setup remote IP access and you need help with DID's then you should definately consult a professional because you will need to have advanced knowledge of setting up a network, a VPN and administering IP stations.
A DID number is simply a direct inward dial number on your switch. For example your direct line phone number would be a DID number.
To find out what your DID range is, go to your switch and type in the command: display dialplan
Anything that says extension will be an extension on your switch and at least some of them will be DID's, find out what the first digit is in your Dial Plan that is DID and then you can search for an available one.
If you have ASA you can us the command called "Find an available extension" and it will automatically find the next one for you.
You will need to either create a new IP station or duplicate one that is already existing with the new DID number you found.
If you have an existing network and VPN then you can either purchase IP hardphones or install IP Softphones on their computers - (make sure you have your Avaya RTU license for your current softphone model)
If you need more help, I will suggest that you break up this request into several categories that you need help with and post them in the "Avaya (Lucent): Definity Systems" forum"
That is a dial range of 1000 numbers. It would be my guess that not all of them are direct lines or DID lines. A DID would be one where you could dial the 10 or 7 digit number from the outside world and reach that extension.
For example in your dial plan (XXX)XXX-1000, is that a direct dial number? If you're not sure, just give a few test calls to different numbers/extensions. It is more than likely that most of them are just inside extensions with only a couple hundred of them being actual direct lines. (Just a guess here - not sure how large your site is!)
