C H A P T E R 22 V.150 Minimum Essential Requirements • V.150 Overview, on page 255 • Configure V.150 Task Flow, on page 255 V.150 Overview The V.150 Minimum Essential Requirements feature allows you to make secure calls in a modem over an IP network. The feature uses a dial-up modem for large installed bases of modems and telephony devices operating on a traditional public switched telephone network (PSTN). The V.150.1 recommendation specifically defines how to relay data from modems and telephony devices on a PSTN into and out of an IP network through a modem. The V.150.1 is an ITU-T recommendation for using a modem over IP networks that support dial-up modem calls. The Cisco V.150.1 Minimum Essential Requirements feature complies with the requirements of the National Security Agency (NSA) SCIP-216 Minimum Essential Requirements (MER) for V.150.1 recommendation. The SCIP-216 recommendation has simplified the existing V.150.1 requirements. Cisco V.150.1 MER feature supports the following interfaces: • Media Gateway Control Protocol(MGCP) T1(PRI and CAS) and E1(PRI) trunks • Session Initiation Protocol (SIP) trunks • Skinny Client Control Protocol (SCCP) for analog gateway endpoints • Secure Communication Interoperability Protocol-End Instruments (SCIP-EI) Configure V.150 Task Flow Complete these tasks to add V.150 support in Unified Communications Manager.
