  • Analog Voice Gateway – One Call Per Port
  • Digital Voice Gateway – Multiple Calls Per Port

A lot of material already covered in CVOICE..

  • H.323 Audio/Video – Peer to Peer (Doesn’t support QSIG)
  • MGCP – Cisco primarily, Server-Client Model. CUCM can control the Gateway almost completely. CUCM dies and so does Voice Gateway!
  • SIP – Universal VoIP standard (Connection to ITSP) – Peer to Peer
