>      Security Level: None
>          Components: Resources/res_xmpp
>    Affects Versions: 11.5.0
>         Environment: CentOS 6.4
>            Reporter: Andrew Nagy
>            Severity: Minor

> Sometimes the Google Voice servers have a bad habit of sending out 1 byte replies to the xmpp resource. When a blank 1 byte reply is received from the socket the buffer attempts to wait (endlessly) for the rest of the reply from google. 
> This effectively blocks the socket and google voice calls will no longer come into the server. 
> This patch allows the xmpp module to correctly detect empty packets and send out ping replies to google. It also sets a socket timeout on the default socket which prevents the xmpp socket from closing and preventing future google voice calls from coming into the server. 
> Furthermore instead of sending an empty reply back to google we send a proper xmpp ping reply back. Finally I have also added several more socket messages (near the end)
