I am going to be deploying 2004 and 1120/1140 IP phones in our various locations. These locations have phone systems in them now that will be taken out and replaced by the IP phones. I have the locations main numbers remote call forwarded to a DID number in our main CS1000M system. That DID number then routes the calls out to an auto attendant where the phones are configured for each location. I need to be able to configue 911 on each phone so that when the user picks up the phone and dials 911 it will display their local (old main) telephone number. Currently, when my test location picks dials 911, I see it in the CS1000M showing their old main number being sent out (I programmed it in ERL and assigned the ERL number to the TN). But when 911 answers the call and we ask what number they see - they say the see the main number for the CS1000M. Do I need to configure ECL as well or is there another/easier way to manage this process?
