Summary:                    [patch] SIPNotify dialplan application
Description: 
It's come up before, regarding having a dialplan application to do
SIPNotify, similar to the cli command 'sip notify'

Avoids the awful way it's currently done in dialplan
exten => 2345,n,System(/usr/sbin/asterisk -rx "sip notify
grandstream-idle-screen-refresh GXP0009")

Only supports one local peer as required for our purpose, which was to
remotely request a refresh of Idle Screen on a Grandstream GXP series phone
with latest firmware 1.1.6.46.

syntax is as simple as
exten => 2345,n,SIPNotify(grandstream-idle-screen-refresh,GXP0009)

code is copied from chan_sip.c:sip_cli_notify with appropriate mods.

---------------------------------------------------------------------- 
Anybody able to help out, the DialPlan needs to know whether the SIP Notify
was accepted or not?
Then after that I can take appropriate dialplan action, right now the
SIPNotify is sent blind. 

If the phone is active (not idle) it will return a 480 response,
Temporarily Unavailable. 

example console output:
    -- Executing [2345 at trusted:1] SIPNotify("DAHDI/33-1",
"grandstream-idle-screen-refresh,GXP0009") in new stack
    -- Sent NOTIFY of type 'grandstream-idle-screen-refresh' to 'GXP0009'
    -- Executing [2345 at trusted:2] Dial("DAHDI/33-1", "DAHDI/32,20") in new
stack
    -- Called 32
    -- DAHDI/32-1 is ringing
    -- Got SIP response 480 "Temporarily Unavailable" back from
192.168.124.51
