I want to use a VOIP phone running out of our main switch to an outside faciltiy but I want the 911 information to show the correct address of that facility. From what i have read I think this is done in Element Manager but do I need to purchase anything else or do I need to contact the 911 office? We are using the nortel cs1000 with telephony manager 3.2. If anyone has a proven walk thru to acheive this I would greatly appreciate it.
