Hi, I would like to ask for expert advice. We have NEC SL1000 and our telephone provider announce that they will update all their customers' telephone number (by adding one digit). How can we update this on SL1000?
Hi @belevedere, thank you for your reply. I check 26-01 : Automatic Route Selection Service settings. Does it mean we are not using ARS and we don't need to do anything with SL1000 once our telephone provider updated our trunkline number?
