====== SIP Notify ======
==== Configuration ====
All these methods require the Message Waiting notification to be configured as SIP or SIP+PMS.

=== Notifications ===
From Mailbox Administration->Templates->Notifications.

Set both the MWI On and MWI Off template to use SIP or SIP + PMS if you prefer. 

===== Direct To Phone =====
Often if the PBX doesn't supply forwarding of message waiting to a phone or is blocked because it has it's own voicemail the DuVoice can send a SIP notify directly to the phone or gateway.

Care should be taken to ensure the PBX never sends a SIP Notify to the extension otherwise the light may not be in the correct state.

==== Requirements ====
  * Phone is configured for a static IP address. This can done on the phone or within the DHCP server which is preferred.
  * Phone must support anonymous SIP notify.
  * DuVoice must be able to send network packets directly to the phone. Ensure their are no proxy servers or network settings which could prevent this.
  * DuVoice must be licensed for SIP.

==== Mailbox ====
Edit a mailbox, choose Address List, and configure one or more of the MWI addresses for the SIP address you wish to send the notification.

===== SIP to Analog Gateways =====
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.
