What is a capability of a Cisco IOS XE media resource?
Answer(s): A
Which two parameters influence the total number of supported conference participants on a Cisco IOS XE router that has DSP modules? (Choose two.)
Answer(s): A,D
An engineer troubleshoots an outbound call failure on an ISDN-PRI circuit. The engineer is suspecting the error "Incompatible Destination". Which debugs or commands are run in the voice gateway to troubleshoot the issue?
Refer to the exhibit. When a call is received on Cisco Unified Border Element, from which IP does it allow a connection?
The ip address trusted list configuration under the voice service voip section in Cisco Unified Border Element (CUBE) defines which IP addresses or subnets are allowed to send SIP requests to the CUBE. If the source IP address of an incoming SIP message is not in the trusted list, the CUBE rejects the connection. The trusted list allows SIP connections only from 192.168.101.201, as it matches the subnet 192.168.101.0/25 in the configuration.
An engineer is configuring a Cisco IOS XE gateway to join three callers together in the same conversation. Which IOS XE media resource must the engineer configure to accomplish this goal?
Answer(s): B
To join three or more callers in the same conversation, a conference bridge is required. A conference bridge is a media resource that mixes multiple audio streams into a single stream, allowing multiple participants to communicate simultaneously.A hardware-based conference bridge uses DSP (Digital Signal Processor) resources to mix audio streams. It is highly scalable and provides better performance compared to software-based solutions, making it ideal for handling multiple participants or high-quality calls.Hardware conference bridges are typically required for real-time audio mixing in larger environments, as they offload the processing to dedicated DSPs on the gateway.
