[OpenSER-Users] Sending IM even when the destination User goes "Offline"

[Cesar Troncoso]

Hello everybody,

Lets suppose a user wants to send an Insant Message to another user of
his contact list whose presence is "offline". Is there a way to store
the message somewhere (another server maybe) for a certain period of
time, so that when the destination user goes on-line again receives the
Instant Message? 

Thank you very much in advanced for your help,

Cesar
