Adding new extensions (SDNs)is easier to do with a PC running a terminal program or the host program. Then you just create an SDN number and enter the actual serial number off the phone.

To do it from just the phone means that I'll have to dig out the manual to be sure, but I somewhat recall that if you wanted to create a new extension using the phone set, you would dial 3 + the new 3-digit extension that you wanted and then dial 7 additional zeros. So creating 126, say, would be 3 + 1260000000.

If that doesn't work, just reply and I'll confirm the sequence. This 126-0000000 method I'm thinking of may have depended upon performing host software programming prior to having the actual serial number set.

I do have the manuals, its just that they're in storage.
