What is mobile and remote access?
The Mobile and Remote Access solution (MRA) supports a hybrid on-premises and cloud-based service model. This provides a consistent experience inside and outside the enterprise. MRA provides a secure connection for Jabber application traffic without having to connect to the corporate network over a VPN.
What is Cisco VCS?
The Cisco Video Communication Server (VCS) provides the most advanced telepresence and video conferencing call control in the industry. Flexible and extensible for video conferencing applications, it enables any-to-any interoperability between all standards-compliant SIP and H. 323 devices.
How is VCS connected to Cisco Unified Communications Manager?
Unified CM and the VCS Control are connected together using a SIP trunk across an IP network; the VCS Control domain is vcs.
What is the difference between Cisco Expressway C and E?
Differences between VCS C and VCS E Tandberg's legacy devices typically used VCS Control, or VCS C, within the organization and VCS Expressway, or VCS E, was used between firewalls. To put it more simply, VCS C was used internally within the organization while VCS E was utilized externally.
What is Cisco TMS?
Cisco TelePresence Management Suite (Cisco TMS) is a portal for managing and monitoring your videoconferencing network from a single, structured interface. Cisco TMS provides centralized control for on-site and remote video systems, and a deployment and scheduling system for your entire video network.
What is Cisco TelePresence conductor?
The Cisco TelePresence Conductor simplifies the use of multi-user video conferencing by intelligently allocating meetings, and optimises the utilisation of resources available on multipoint conferencing servers (MCUs).
What is Cisco Expressway C?
Cisco Expressway is designed specifically for comprehensive collaboration services. It features established firewall-traversal technology and helps redefine traditional enterprise collaboration boundaries, supporting our vision of any-to-any collaboration.
How does Cisco Call Manager work?
CUCM uses SIP or SCCP to communicate with Cisco IP Phones for call setup and teardown and for supplementary service tasks. After a call has been set up, media exchange occurs directly between the Cisco IP Phones across the IP network, using the Real-Time Transport Protocol (RTP) to carry the audio.
What is VCSE machine?
VCSE is a system for studying cyber threats on control-system dependent infrastructures. It is a hybrid system to support Simulated, Emulated, and Physical components for Investigative Analysis (SEPIA).
What is mobile and remote access?
The mobile and remote access solution supports a hybrid on-premises and cloud-based service model, providing a consistent experience inside and outside the enterprise. It provides a secure connection for Jabber application traffic without having to connect to the corporate network over a VPN. It is a device and operating system agnostic solution for Cisco Unified Client Services Framework clients on Windows, Mac, iOS and Android platforms.
What is VCS caching?
The VCS caches endpoint credentials which have been authenticated by Unified CM. The caching of credentials reduces the frequency with which the VCS has to submit endpoint credentials to Unified CM for authentication, and thus improves system performance.
What is diagnostic logging in VCS?
The diagnostic logging tool in VCS can be used to assist in troubleshooting system issues. It allows you to generate a diagnostic log of system activity over a period of time, and then to download the log.
Why does a high volume of calls trigger denial of service thresholds on unified CM?
This is because all the calls arriving at Unified CM are from the same VCS Control (cluster).
Is unified CM impacted by VCS?
The Unified CM dial plan is not impacted by devices registering via VCS. Remote and mobile devices still register directly to Unified CM and their dial plan will be the same as when it is registered locally.
Do VCS deployments require SIP trunks?
VCS deployments for mobile and remote access do not require SIP trunk connections between Unified CM and VCS Control. Note that the automatically generated neighbor zones between VCS Control and each discovered Unified CM node are not SIP trunks.
