int cr_load_next_domain (struct sip_msg *_msg, gparam_t *_carrier, gparam_t *_domain, gparam_t *_prefix_matching, gparam_t *_host, gparam_t *_reply_code, gparam_t *_dstavp)
Loads next domain from failure routing table and stores it in an AVP.

Module; CARRIERROUTE :: The Kamailio carrierroute Module

Definition in file cr_func.h.

Function Documentation

int cr_load_next_domain	(	struct sip_msg *	_msg,
		gparam_t *	_carrier,
		gparam_t *	_domain,
		gparam_t *	_prefix_matching,
		gparam_t *	_host,
		gparam_t *	_reply_code,
		gparam_t *	_dstavp
	)

Parameters:

	_msg	the current SIP message
	_carrier	the requested carrier
	_domain	the requested routing domain
	_prefix_matching	the user to be used for prefix matching
	_host	the host name to be used for rule matching
	_reply_code	the reply code to be used for rule matching
	_dstavp	the name of the destination AVP

Returns:: 1 on success, -1 on failure

int cr_load_user_carrier	(	struct sip_msg *	_msg,
		gparam_t *	_user,
		gparam_t *	_domain,
		gparam_t *	_dstavp
	)

Parameters:

	_msg	the current SIP message
	_user	the user to determine the carrier data
	_domain	the domain to determine the domain data
	_dstavp	the name of the AVP where to store the carrier id

Returns:: 1 on success, -1 on failure

int cr_nofallback_route	(	struct sip_msg *	_msg,
		gparam_t *	_carrier,
		gparam_t *	_domain,
		gparam_t *	_prefix_matching,
		gparam_t *	_rewrite_user,
		enum hash_source	_hsrc,
		gparam_t *	_dstavp
	)

The difference to cr_route is that no fallback rule is chosen if there is something wrong (behaves like now obselete cr_prime_route)

Parameters:

	_msg	the current SIP message
	_carrier	the requested carrier
	_domain	the requested routing domain
	_prefix_matching	the user to be used for prefix matching
	_rewrite_user	the localpart of the URI to be rewritten
	_hsrc	the SIP header used for hashing
	_dstavp	the name of the destination AVP where the used host name is stored

Returns:: 1 on success, -1 on failure

	_prefix_matching	the user to be used for prefix matching
	_rewrite_user	the localpart of the URI to be rewritten
	_hsrc	the SIP header used for hashing
	_dstavp	the name of the destination AVP where the used host name is stored
