Overview/Description The growing use of mobile devices allows users - whether on a retail floor, at an airport, or at a Wi-Fi hotspot in a local coffee shop - to enjoy the efficiencies and speed of Cisco Unified Communications. However, as more people own multiple devices ranging from office phones to home-office phones, laptop computers to mobile phones, they spend more time managing their communications across phone numbers and voice mailboxes, limiting their ability to accomplish work efficiently. Cisco Unified Mobility allows users to be reachable at a single number, regardless of the...

Overview/Description Users of a phone system often need to reach various destinations, such as extensions within the same site, different sites (sometimes with different dialing plans) within the same company, and other companies within the same country or in different countries. Because these calls can take different paths, such as the IP WAN or a preferred public switched telephone network (PSTN) carrier, completing the calls often requires dialing various access codes, numbers of digits, or prefixes. In addition, restricting certain destinations, such as 900 numbers, is often prudent. To...

Overview/Description To place external calls, Cisco Unified Communications Manager (Cisco Unified Communications Manager) deployments need a connection to the public switched telephone network (PSTN). Such connections are provided by gateways, which connect traditional telephony interfaces (such as digital or analog trunks) and VoIP domains. Gateways can be integrated in Cisco Unified Communications Manager by using different protocols such as Media gateway Control Protocol (MGCP), H.323, or Session Initiation Protocol (SIP) for signaling on VoIP call legs. This course describes the role and...
