* History:
* --------
* 2006-04-14 initial version (bogdan)
* 2006-11-28 Added statistic support for the number of early and failed
* dialogs. (Jeffrey Magder - SOMA Networks)
* 2007-04-30 added dialog matching without DID (dialog ID), but based only
* on RFC3261 elements - based on an original patch submitted
* by Michel Bensoussan <michel@extricom.com> (bogdan)
* 2007-05-15 added saving dialogs' information to database (ancuta)
* 2007-07-04 added saving dialog cseq, contact, record route
* and bind_addresses(sock_info) for caller and callee (ancuta)
* 2008-04-14 added new type of callback to be triggered when dialogs are
* loaded from DB (bogdan)
* 2010-06-16 added sip-router rpc interface (osas)
