[Freeswitch-users] send event to Grandstream phones when presence/dialog event has sent

Hi 1. I would like to send an event when presence or dialog events are sent. Because i have Grandstream phones, and i want to refresh their IdleScreens as it can be read the lower part of this page: http://www.voip-info.org/wiki/view/GXP-2000+XML+Idle+Screen Have i modify the code of sofia_presence.c or is there a simpliest way to send events bound to an other event? 2. And could you give an idea how can i insert records in the simpliest way to the database also when presence/dialog event sent? (Or is the simpliest to give code to sofia_presence.c?) Thank you Robert
