[Freeswitch-users] Presence Server

i try to use the LED´s on the Phone to sgive user a indication of the state of my Phone is redirected or ithis Phone is subscribed in a Queue. For this i use a free extension in sample 1000 and put on the Phone the LED to BLF 1000. This Works until the phone subscribe again after 3600 sec. The my manipulation will be lost in the presence server. So i need a way to take care about this state. Is there a common solution for this issue ? regards
