Contribution to Improving the Presence Base of VoIP Servers for Sending and Receiving Messages

The purpose of this article has been emphasized on the SIP Signaling Protocol in order to contribute to the improvement on sending and receiving message about the services provided by the VoIP servers. The current configuration of VoIP servers has allowed us to see that if a user connected by wifi to the VoIP server has disconnected involuntarily from the network without disconnecting his SIP client from the server, the server can not remove him from his base presence, where it stores all connected users, and cost the message that is sent to him is not stored and no longer he does not receive it.
To overcome this, we couple the Freeswitch intelligence used as a VoIP server coupled to a presence detection server and a MySQL database. This platform makes it possible to retrieve all messages with a non-connected recipient and store them in a database, then wait for their reconnection to send them the messages that concern them.
