====== To Gateway ======

===== Preface =====

  * This page is for setting up the DuVoice server to send MWI updates to a SIP Gateway.
  * Compared to direct-to-phone method, the direct-to-gateway method only has one solution. 
  * Which is sending the SIP notify to an IP address of the gateway. 
    * (And postpending the port number, if needed).

===== Requirements =====

  * Networking:
    * The DuVoice server's Dialogic HMP Telephony drivers only allow for one NIC to be assigned for SIP.
      * Thus all SIP traffic will need to be routed through this NIC.
        * Only 1 IP address is supported on this NIC.
        * This NIC will need to have network access to both the PBX and the gateways.
          * If PBX is a hosted solution, then this NIC will need internet access as well.
    * Must have 2-way SIP traffic between:
      * Each gateway itself.
      * And the Dialogic-HMP-bound network interface of the DuVoice server.
        * Meaning these devices must be on the same network.
          * Or have the routing rules in place to support this.
    * The physical gateway must remain on the same IP address.
      * This can be done one of two ways:
        * Manual static IP configuration.
        * DHCP reservation.
      * If at some point the physical gateway is replaced:
        * Keeping the new one on the same IP address will minimize further troubles.
          * If the IP changes:
            * MWI will cease function until:
              * And the associated mailboxes to that gateway will need to be updated.





===== SIP Gateway Configuration =====

  * Requires the gateways to be assigned a static IP address.
    * This information will require exporting into a list.
      * We'll refer to this as ''<gateway-ip>'' in the DuVoice configuration below.
  * If the gateway maps a single IP address to a single phone, this is the ideal scenario.
    * If it uses a port number instead. The DuVoice configuration will require this information.
      * We'll refer to this as ''<gateway-port>'' in the DuVoice configuration below.
  * All of this information will need to be organized so that it maps to the correct extension number so the correct MWI updates can be sent to the correct extension.

==== Model Specific Configuration ====

When using a SIP gateway to connect analog phones, many support the ability to address an extension directly allowing the DuVoice system to send a SIP notify to the gateway.

Some Gateways only use use the gateway IP address for each port while others like the Grandstream GXW4224V2 use the IP address and a port number for each jack. In the case of the Grandstream 

=== Issues ===
  * The Gateway must support the type of MWI light the analog phone uses and must be set accordingly. Grandstream GXW4224V2 and Adtran 924e supports both FSK and NEON.

===== DuVoice Configuration =====

==== Mailbox Configuration ====

For this to work, we need to enter the IP address of the phone (or gateway IP and port) within the mailbox's configuration.

=== CSV Import ===

For more information on the CSV import process [[vs8:vsconfig:file:importcsv|here]].

  - Configure the MWI address into the 'MWI 0' column to the CSV file:
    - For a SIP gateway configure it like this example:
      - 123@192.168.0.123:5003 
        - Replace the ''123'' with the ''<phone-ext>''.
        - Replace the ''192.168.0.123'' with the ''<gateway-ip>''.
        - Replace the ''5003'' with the ''<gateway-port>''.
        - Keep in mind that this information needs to be in the same row as the appropriate mailbox.

=== Manual Configuration ===

  - Log in to the desktop of the DuVoice server.
  - Open the 'DV2000 Manager' application.
  - Click on the 'Mailbox' drop down option.
  - Click on the 'Management' option.
    - The 'mailboxes' window will open.
  - Navigate to the mailbox to be modified.
  - Double click on it to edit.
    - The individual mailbox will open.
  - Click on the 'MWI' option on the left.
  - Configure the MWI address into the 'Address' column for 'Position' 0 like the following:
    - For a SIP gateway configure it like this example:
      - 123@192.168.0.123:5003 
        - Replace the ''123'' with the ''<phone-ext>''.
        - Replace the ''192.168.0.123'' with the ''<gateway-ip>''.
        - Replace the ''5003'' with the ''<gateway-port>''.
  - Click 'ok' to save changes, and close the window.
