    1. MGCP SRST
    2. SRST fallback
    3. MGCP fallback
    4. MGCP in SRST mode

  3. What can you use to configure the dial plan at the remote-site gateway so that branch users can still reach the headquarters when dialing internal directory numbers during fallback?

    2. SCCP
    3. SIP
    4. H.323
    5. Megaco
    6. RTP

  5. What IOS commands are used on a remote gateway configured with MGCP fallback to give PSTN access for IP Phones during fallback mode?

    1. This feature is unavailable. Remote phones can only dial each other.
    2. H.323 or SIP dial peers.
    3. Static routes.

    2. SIP can be routed through the PSTN with POTS dial peers.
    3. SIP can be routed through the PSTN if the local exchange carrier enables SIP through the PSTN connection.
    4. SIP can be routed through the PSTN with POTS dial peers combined with the local exchange carrier, enabling SIP through the PSTN connection.

  8. What are two requirements to have multiple MOH sources in SRST?

    1. This is not possible.
