Summary:                    Unsolicited SIP notifies cannot be routed to MWI
lights on individual phones
Description: 
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.

cmaj, i'm going to get a 1.8 box up and running here to test, but i'm
curious as to how exactly you had your trunks to exchange 2010 setup?

What does exum2010 represent? I'd like to help out in documenting this so
it's easy for others to follow. This is GREAT news that we can finally make
this work!
