dial-peer voice 2 voip
  destination-pattern 78....
  progress_ind setup enable 3
  progress_ind progress enable 8
  voice-class codec 1
  voice-class h323 1
  session target ipv4:x.x.x.x
  dtmf-relay h245-alphanumeric
  fax-relay ecm disable
  ip qos dscp cs3 signaling
  no vad

dial-peer voice 3 voip
  preference 1
  destination-pattern 78....
  progress_ind setup enable 3
