How do i program my nortel m5316 for call forwarding numbers?

Depending what system your provider is using it can either be done by you at home or they will have to set it. If you call your provider they will help you or they will fix it. Each ring is set at 6 second intervals so if you have 3rings that is 18 seconds. If you was 6 rings then ask for 36 seconds etc. hope this helps

The phone can get some power from the loop like a basic telephone. That should suffice to make phone calls.

But many of the advance features and display options cannot work on loop power alone. You have to get a special plug that plugs into the wall AND the phone jack. Then plug the phone into that.

I am not aware of any battery in the phone.

That will require a programming change for your extension. If you are familiar with programming it is located under the capabilities heading and listed next as Forward NoAnswer - press show twice then next and you can use the CHNG soft key to change the delay before being forwarded.

If you switched phone companies and the feature stopped working you probably had Call Forward Busy/No Answer from AT&T. If you use the call forwarding in the phone it will use two phone lines for the entire length of the call. Call Comcast and have them add Call Forward Busy/No Answer and tell them the number you would like your calls forwarded to and the ring cycle (the number of rings on no answer).

Your options are...

Option 1: Hit 7 then 2 then #. You'll hear an interrupted dial tone. Then dial the number you're forwarding to.
To cancel hit 7 then 3 then #.

Option 2: Hit * then 7 then 2. You'll hear an interrupted dial tone. Then dial the number you're forwarding to.
To cancel hit * then 7 then 2.

The Nortel call forwarding (feature 4) is for forwarding the ringing and intercom from one extension to another.ex. if you were going to be working in the conference rm. instead of at your desk,with the forward on to the conference rm. extension, the calls you get at your desk will transfer to the conference rm. phone. Call forwarding through your service provider is done by accessing the telephone line you wish to forward, dial *72 (you should get dialtone reordered)and dial the telephone number to where you want the calls to be forwarded to. the party on where your forwarding the line to has to answer the line for the forward to take place. to remove call forwarding , access the line you have the forward on and dial * 73, you should recieve a stuttered dialtone for confirmation that the service is off

The DN may not be configured to allow forwarding to an outside line for security reasons. I think the default is 4 digits. You will need to talk to whomever programs your switch and ask them to allow this feature.

You can set divert for the calls to another number. Do check for the call settings and activate the divert based on situation like.. When busy. Not reachable.

turn on feature 84.... turn off feature # 84

Use * for the pause.
