int domainpolicy_db_bind ( const str *  db_url  ) 

Bind the database interface.

Parameters:
db_url database url
Returns:
-1 on failure, 0 on success

void domainpolicy_db_close ( void   ) 

Close the database connection.

References db_func::close.

int domainpolicy_db_init ( const str *  db_url  ) 

Initialize the database connection.

Parameters:
db_url database url
Returns:
-1 on failure, 0 on success

int domainpolicy_db_ver ( const str *  db_url,
const str *  name 
)

Check the database table version.

Parameters:
db_url database URL
name table name
Returns:
-1 on failure, positive database version on success

int dp_apply_policy ( struct sip_msg *  _msg,
char *  _s1,
char *  _s2 
)

Apply DP-DDDS policy to current SIP message.

Apply DP-DDDS policy to current SIP message. This means build a new destination URI from the policy AVP and export it as AVP. Then in kamailio.cfg this new target AVP can be pushed into the destination URI $duri

Parameters:
_msg SIP message
_s1 unused
_s2 unused
Returns:
negative on failure, positive on succes
