I am trying to set up 911 dialing in our 3CX system. We have a headquarters office and then a few different remote sites that all connect to our 3CX server at our headquarters office. If someone dials 911 from the remote offices, however, they obviously need to be given the correct address of that site instead of our headquarters. We use Flowroute for our trunk line and when I was setting up e911 for our DIDs, you have to pay a fee per DID to have an address associated with it. We have several hundred DIDs and the fee would be pretty large. What is the best way everyone has set up 911 dialing? I want to keep the cost as much to a minimum as possible. Is there a way to set up an outbound rule that says if someone from a certain extension group dialing 911 has a different DID than they would calling any other number? That way we could just use one DID per site for 911 dialing and save money instead of giving every single DID an e911 address.
