What is Cisco Mobile Remote Access?
The Cisco Mobile and Remote Access (MRA) feature is a “client edge” solution that allows external software and hardware clients to register to enterprise Cisco Unified Communication (UC) solutions without requiring 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 Jabber MRA?
It is a device and operating system agnostic solution for Cisco Jabber clients on Windows, Mac, iOS and Android platforms. MRA allows Jabber clients that are outside the enterprise to do the following: Use Instant Messaging and Presence services. Make voice and video calls. Search the corporate directory.
What is the difference between VCS and expressway?
The VCS series is better suited for customers who use video communication only and have no need to support voice over IP phones and other voice related services. The Expressway series, on the other hand, is more suited for customers who need to support voice over IP phones or other voice related services.
How does Cisco TelePresence work?
Cisco TelePresence supports presentation sharing for point-to-point and multi-point meetings. Auto Collaborate is a unique feature that allows users in all rooms to instantly see data or video and hear audio output from the following sources: A laptop (for example, a presentation or movie). See Connecting a Laptop.
What are MRA phones?
Basically, MRA (Cisco Unified Communications Mobile and Remote Access) allows endpoints such as Cisco Jabber to have their registration, call control, provisioning, messaging and presence services provided by CUCM when the endpoint is outside the enterprise network.
What is the purpose of mobile and remote access MRA in the Cisco UCM architecture?
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.
How do you set up an MRA?
0) - MRA Configuration [Cisco Expressway Series] - Cisco....ProcedureOn the Expressway-C, go to Configuration > Unified Communications > Configuration.Set Unified Communications mode to Mobile and Remote Access.Click Save.Repeat this procedure on Expressway-E.
What is Cisco expressway used for?
Cisco Expressway is a powerful gateway solution specifically designed for comprehensive collaboration services provided through Cisco Unified Communications Manager, Cisco Business Edition, or Cisco Hosted Collaboration Solution (HCS).
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).
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 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.
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.
What is Cisco Unified Communications?
Cisco Unified Communications mobile and remote access is a core part of the Cisco Collaboration Edge Architecture. It allows endpoints such as Cisco Jabber to have their registration, call control, provisioning, messaging and presence services provided by Cisco Unified Communications Manager (Unified CM) when the endpoint is not within the enterprise network. The VCS provides secure firewall traversal and line-side support for Unified CM registrations.
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.
What is off-premises access?
Off-premises access: a consistent experience outside the network for Jabber and EX/MX/SX Series clients
Can a third party SIP device register to Expressway C?
Third-party SIP or H.323 devices can register to the Expressway-C and, if necessary, interoperate with Unified CM -registered devices over a SIP trunk.
