Hello Mojtaba,

please keep the list in CC.

The htable module support this memory storage and also auto-expiration out of 
the box. :-)

You can find (a bit complicated) example in the usrloc module. A starting 
point for the expiration logic can be the delete_ucontact(..) function there. 
You need to store the SIP message data in a proper data structure like a list 
or a hash table.

Best regards,

Henning
