Some of the major supported integration methods are the following:
Skinny Client Control Protocol (SCCP) with Cisco Unity
Simplified Message Desk Interface (SMDI)-capable voice-mail system with CallManager through a Media Gateway Control Protocol (MGCP) gateway or with a VG-248
Cisco Digital PBX Adapter (DPA) integration for Octel or Nortel Meridian voice mail systems
CTI/TSP integration for other systems
