------------------------------------------------

Greetings Alexr1,

This patch allows a sip trunk or other device to send unsolicited sip notifies (usually for MWI) to the sip trunk. It doesn't do anything beyond allowing Asterisk to be able to receive these notifies. Other Asterisk code then relays them to wherever they end up.

As to the event queuing, and how they get sent to the phone, I'm afraid that discussion isn't related to this patch.

I'm glad to hear the reception end of the code is working for you though.

> Currently, the implementation for unsolicited_mailbox routes all inbound unsolicited sip notifies to a single mailbox at the hard coded context SIP_Remote.
> This makes it impossible for 3rd party SIP integrations to light MWI lights on phones attached to Asterisk. This is critical for 3rd party applications such as voicemail and IVR systems (IE: Exchange UM and Callware Callegra) to fully integrate with Asterisk as they can with other PBX systems such as Cisco Unified Communications Manager. 
> For these types of integrations, Asterisk needs the ability to receive unsolicited SIP notifies and route them as MWI lights to the appropriate physical device, within a context defined per trunk. This needs to occur without breaking anyone relying on the current Asterisk functionality of routing all unsolicited sip notifies to a single box.
> The submitted patch handles this as follows:
> If unsolicited_mailbox is unset, unsolicited notifies are not delivered anywhere.
> If unsolicited_mailbox=somebox all unsolicited notifies will be delivered to somebox at SIP_Remote to preserve existing functionality.
> If unsolicited_mailbox=somebox at somecontext all unsolicited notifies will be delivered to somebox at somecontext
> If unsolicited_mailbox=@somecontext the box from the sip notify will be used to deliver the sip notify to the specified box at somecontext.
> The box is specified either through the Message-Account portion of the body, and if unspecified there, the To header, as specified in RFC3842. 
> Additionally, this patch adds debug logging so that an end user can troubleshoot unsolicited sip notify issues by turning on debug logging.
> ****** ADDITIONAL INFORMATION ******
> This issue supersedes issue 18736. Thanks also go to cmaj for his submission of the UM patch and additional guidance as we created this patch.
