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.
  

• int calc_contact_q (param_t *_q, qvalue_t *_r)

  Calculate contact q value as follows: 1) If q parameter exists, use it 2) If the parameter doesn't exist, use the default value.
  

• int check_contacts (struct sip_msg *_m, int *_s)
