第9题:
RSVP is a required configuration to support conference calls without voice packet loss.
The QoS configuration on the 831 router must always provision sufficient bandwidth for two RTP streams.
Call admission control is an issue only when using hardware DSP resources.
When using the conference call features on a 7960 IP phone, only one RTP stream is present regardless of how many extensions are on the conference.
第10题:
Call Admission Control
TAPI
MGCP
SRST
第11题:
provide far-end call control
provide far-end camera control
translate analog voice to packetized voice
transition call path between different networks
provide locations-based call admission control
第12题:
A Voice over IP (VoIP) packet consists of the voice payload, IP header, TCP header, RTP header, and Layer 2 link header.
The voice carrier stream uses H323 to set up, maintain, and tear down call endpoints.
Call control signaling uses Real-Time Transport Protocol (RTP) packets that contain actual voice samples.
The sum of bandwidth necessary for each major application, including voice, video, and data, should not exceed 75 percent of the total available bandwidth for each link.
第13题:
Which two are functions of an IP voice gateway?()
第14题:
When calls are denied by call admission control (CAC), the calls are rerouted through the PSTN via the use of which Cisco CallManager feature?()
第15题:
Which two Internet Protocol (IP) telephony devices are best categorized as infrastructure components? ()
第16题:
Two sites are using a multisite centralized call processing model. The voice gateway on the remote branch has lost IP connectivity to its Cisco CallManager server. Which feature enables the remote gateway to take the role of the call agent during the WAN failure? ()
第17题:
A company is using a multi-site centralized call processing model. Which feature ensures that theremote site IP phones will still have limited functionality given a WAN outage?()
第18题:
Which IP telephony deployment model uses an H.225 Gatekeeper-Controlled trunk for call admission control within existing H.323 environments?()
