CWMS Architecture Audio Integration
• G.722 recommended. G.729/711 supported as well. TLS/sRTP supported • CWMS has no echo cancellation. Consider with PSTN and TDM PBX
integration. • SIP Trunks to/from CUCM/SME • Can go into TDM PBX from CUCM/SME • Through SME, no cluster limit • Call-back Teleconferencing
Just like WebEx, this is what it's engineered for (Best End User experience)
• Dial In Operations (Toll free, toll, non-DID) Uses SIP Refer to get to right media server (always)

CWMS Architecture SMTP Integration
• Email essential to CWMS for provisioning and password resets
• Is one of the first things configured upon install
• Self provisioning works as follows ‒ When user is imported they are sent an email
‒ In body of email, they click on link and begin provisioning process
Set Password, location, time zone, language
‒ Auto provisioning with SSO, user simply logs in
• Password resets user receives email

CWMS Architecture Authentication and Directory - SSO
• What is SSO?
• IdP - Identity Provider ‒ Provided by customer’s Identity Management System
‒ Example OpenAM, ADFS, Ping Identity
• SP - Service Provider ‒ WebEx, CWMS
• Directory ‒ Active Directory
• SSO-enabled Client ‒ Browser
‒ WebEx Assistant
• SAML 2.0 ‒ Typically used / designed for cloud environments
‒ can be used internally
Cisco Confidential © 2010 Cisco and/or its affiliates. All rights reserved. 29
CWMS Architecture Authentication and Directory - SSO
• SAML 2.0 IdP support only
• 2 ways to deploy
• SP Initiated Recommended and secure for CWMS
SP (or CWMS in our case) collects the authentication
Credentials are sent to IdP (ex. ADFS or OpenAM)
Pass/Fail sent back
• IdP initiated SP redirects initial collection of credentials to customer provide web server
Considered more secure, but more complex
Cisco Confidential © 2010 Cisco and/or its affiliates. All rights reserved. 30
CWMS Architecture Authentication and Directory - SSO
• SSO only used to authenticate • Still need user DB,
import .csv…or… • Can emulate complete LDAP
authentication and DB synch by: ‒ Enable SSO
‒ Enable Auto Account Creation and Auto Account Update
• LDAP synchronization coming in a few months

CWMS SIP Routing Basics with CWMS
• CWMS must be front-ended with CUCM
• CWMS is web-based and “wants” to out-dial ‒ It is the way it was intended to be utilized, although many misuse it (user training)
• CWMS of course supports dial-in as well ‒ If you dial into CWMS, it must collect meeting ID and get you into the right server
• For Inbound calls ‒ Calls from CUCM must be directed to SIP “Load Balancer”
‒ SIP Load Balancer targets (2 of the Media VMs) are provided to you upon provisioning the system
‒ Initial Calls from CUCM to SIP LB should be done in “circular” fashion using RGs and RLs
‒ From there, CWMS must process calls and hold meetings on “application” server
• Two Trunk Types ‒ CUCM SIP messages with CWMS “load balancer” servers
‒ CUCM SIP messages with CWMS “application”servers
© 2013 Cisco and/or its affiliates. All rights reserved. Cisco Public
CWMS High Availability and Routing for SIP (2000 Port Model)
The Concept of VIPs (discussed later) do not apply to SIP, only Web SIP HA from CUCM to CWMS handled by CUCM routing mechanisms (RLs and RGs) Also, you can utilize SIP OPTIONS ping for smoother failover SIP HA for inbound calls
1. The SIP “Load Balancer” receives all initial inbound SIP requests (but never terminates actual media)
2. Caller Calls from CUCM to a server via RG/RLs 3. The SIP “Load Balancer” immediately does a SIP 3XX redirect of caller to one
of the media servers for IVR processing. There is no guarantee at this point that you are on the right media server where the meeting is in progress. This uses SIP Route patterns in CUCM and can go to any of the Media VMs
4. The IVR on the media server collects the meeting ID (DTMF) 5. The IVR does a SIP REFER to the media VM where the meeting is in
progress (assuming it is on a different server). This uses the same SIP route patterns in CUCM and can go to any of the Media VMs.
SIP HA for out-dial, CWMS simply generates call to number from the media server where the active meeting is being held and none of the above matters

CWMS High Availability and Routing for SIP Summary
Therefore, with CWMS Architecture We have 2 types of trunks
“Load Balancer” Trunks and “Application Server” Trunks
Because CUCM can’t trunk to same IP address on same ports, we utilize different port numbers. This equates to two CUCM SIP Security Profiles
In 2000 port deployment model with HA We have 2 trunks to the “load balancer” functionality
We have 4 trunks to support Refers/Redirects (one for each Media)
In 50/200/800 port deployment model with HA We have 2 trunks to the “load balancer” functionality
We have 2 trunks to support Refers/Redirects (one for each Media)
Use SIP OPTIONS pings

CWMS High Availability for Web Traffic - Split DNS example
‒ We use Virtual IP addresses (VIPs) that works like HSRP, same L2 network, replying to ARPs appropriately ‒ Admin/Media VMs on inside handle Private VIP for Web Traffic (web meetings and administration) ‒ IRPs handle the Public VIP (for external web traffic coming in) ‒ Heartbeat communication for VIPs happens between the real IP addresses ‒ When active Admin/Media VIP or IRP VIP fails, the backup takes over and starts responding to ARP for the VIP ‒ Split DNS (described later), the meeting URL points to internal server VIP (inside attendees) and the IRP server
VIP (external attendees) ‒ Administration URL points to internal server VIP

CWMS Web Traffic Routing In Action (2000 port as example)
Basic Web High Availability and Routing Example 1. Initial Web request comes in to VIP
2. Active server responds to ARP request for the .1 address below
3. Load Balancer functionality provides client list of servers based off of capacity/load calculations
4. Client connects to its Web server. Multiple servers may be employed for the same meeting in heavy load. Here, client was connected to an overflow server
5. cascading may occur (transparent to client)

• Simplified Installation plays into a simplified DR strategy
• Installation by .ova file
‒ Open Virtualization Archive file (zipped Open Virtualization Format, or OVF, files)
‒ SW on the vdisk
• VMware Scripted Installation
‒ Requires v-Center
‒ Contains properties file, asks for all networking information, then performs scripted installation
‒ Install the admin VM first
‒ Web in, then choose Manual or Automated
‒ Automated deploys all VMs for you

• No Geographic redundancy HA yet
• Must be on the same L2 network with no latency • Disaster Recovery
‒ Basically a Geographically placed cold-standby
‒ Have full .OVA ready at all times
‒ Backups on simple NAS/NFS share
‒ Replicate NFS data to another store in secondary data center. Includes Recordings and Backups
‒ Re-install product (Manual or Auto Deploy). Very quick and easy
‒ Make sure newly installed system is pointed to backup NAS/NFS share
‒ When CWMS sees backup file on NAS, provides option to initialize DR

CWMS DNS and Traffic Flow
• DNS For ‒ Admin URL (ex. https://meetadmin.cisco.com) ‒ Meeting URL (ex. https://meet.cisco.com)
• Two DNS Options ‒ Flat DNS, or “non-split-horizon DNS” ‒ Split DNS, or “split-horizon DNS” ‒ This is in regards to the meeting URL (ex. https://meet.cisco.com) ‒ Important, b/c it affects the traffic flow
• Flat DNS ‒ Resolves meeting URL to the same IP address for internal and external users ‒ All meeting traffic flows through the IRP
• Split DNS ‒ Internet DNS resolves meeting URL to the IRP on DMZ
Traffic from Internet flows through the IRP ‒ Internal DNS resolves to internal server
Traffic from internal network goes straight to internal web server.
© 2013 Cisco and/or its affiliates. All rights reserved. Cisco Public
CWMS DNS and Traffic Flow – Flat DNS
• External Client 1. DNS request to https://
meeting.cisco.com 2. DNS responds with VIP of IRP 3. HTTP traffic from external client to IRP 4. IRP reverse proxies traffic to internal
CWMS server where mixing occurs
• Internal Client 1. DNS request to https://
meeting.cisco.com 2. DNS responds with VIP of IRP 3. HTTP traffic from internal client to IRP 4. IRP reverse proxies traffic to internal
CWMS server where mixing occurs
