Functions
void	calc_contact_expires (struct sip_msg *_m, param_t *_ep, int *_e)
	Calculate absolute expires value per contact as follows: 1) If the contact has expires value, use the value. If it is not zero, add actual time to it 2) If the contact has no expires parameter, use expires header field in the same way 3) If the message contained no expires header field, use the default value.
int	calc_contact_q (param_t *_q, qvalue_t *_r)
	Calculate contact q value as follows: 1) If q parameter exist, use it 2) If the parameter doesn't exist, use default value.
int	check_contacts (struct sip_msg *_m, int *_s)
	Check if the originating REGISTER message was formed correctly The whole message must be parsed before calling the function _s indicates whether the contact was star.
contact_t *	get_first_contact (struct sip_msg *_m)
	Get the first contact in message.
contact_t *	get_next_contact (contact_t *_c)
	Get next contact in message.
int	parse_message (struct sip_msg *_m)
	Parse the whole message and bodies of all header fields that will be needed by registrar.
