Hi
Is there anyway to send a notify message to a cisco phone with sip firmware to reset or restart it like this link:
http://www.freepbx.org/forum/freepbx/tips-and-tricks/cisco-9971-phone-configuration-working-example-with-setup-tips

The following variables and functions should be included in sip_notify_custom.conf settings: 
[cisco-restart]
Event=>service-control
Subscription-State=>active
Content-Type=>text/plain
Content=>action=restart
Content=>RegisterCallId={${SIPPEER(${PEERNAME},regcallid)}}
Content=>ConfigVersionStamp={0000000000000000}
Content=>DialplanVersionStamp={0000000000000000}
Content=>SoftkeyVersionStamp={0000000000000000}

[cisco-reset]
Event=>service-control
Subscription-State=>active
Content-Type=>text/plain
Content=>action=reset
Content=>RegisterCallId={${SIPPEER(${PEERNAME},regcallid)}}
Content=>ConfigVersionStamp={0000000000000000}
Content=>DialplanVersionStamp={0000000000000000}
Content=>SoftkeyVersionStamp={0000000000000000}
