CICD – Ch2 – Unified Collaboration
Unified Collaboration
- More than just VOIP
- Bring all collaboration into a seamless framework
- Includes: voice, video and data
- CICD covers core solutions
- CME – Communications Manager Express
- CUCM – Cisco Unified Communications Manager
- CUC – Cisco Unity Connection
- CUIMP – Cisco Unified IM and presences
- There are more outside of this exam
- Contact Center
- WebEx
- Telepresence
- Spark
Communications Manager Express
- Runs IP telephony on an ISR (integrated services router)
- ISR can terminate analog and digital circuits
- FXO, FXS, T1
- FXO – Office, connects to POTS circuits
- FXS – Station, connects to endpoints, analog phones, fax, modem
- Supports VOIP endpoints
- Features: conference calls, video, automatic call distribution
- FXO, FXS, T1
- Platform dependent on number of supported phones
- ISR4451, can handle 450 phones
- All in one device for controlling phones and trunking to PSTN
CME Features
- Call processing and device control
- CLI or GUI based configuration
- Local directory service
- Computer Telephony Integration (CTI)
- Control a device remotely. Example, have jabber make calls using your desk phone
- Trunk to other voice systems
- Integration with Unity Express
- Runs on modules installed in router
- Provides voicemail features
CME and IP Phones
- CME controls virtually every action performed on phone
- SCCP (skinny) or SIP used for signaling protocols to allow CME to communicate and control the phone
- CME instructs phones where to connect, establish calls
- Not involved in the RTP stream of traffic
- CME is not required after a call has been setup
- Exception: If call is going to PSTN that is attached to the CME router
CUCM
- Linux based, VMware guest
- Provides core device control, call routing, permissions, features, connectivity to outside applications
- GUI based administration
CUCM Key Features
- Full audio and video support
- Appliance based operation
- VMware install, on supported hardware
- Redundant server cluster
- Single CUCM cluster can handle 40000 phones running SIP or SCCP
- Megacluster can handle 80000 phones
- Intercluster trunk and Voice Gateway control
- Built in disaster recovery
- Done through sFTP
- Directory service support and integration
- Built-in or LDAP
- Database replication
- Publisher replicates read-only database to subscribers in the cluster
- Run Time Data
- Intercluster communication signaling (ICCS)
- All servers in cluster form TCP connectionn for ICCS over TCP ports 8002-8004
- Assuming 10,000 busy hour calls = 1.5Mbps per server
- Changes to database are performed on Publisher
- Standard cluster supports single publisher and 19 subscribers
- 8 for call processing
- 11 other subscribers can be TFTP, conference bridge, MOH, annunciater
- TFTP is critical for phone and gateway operations
- Bulk of config is downloaded from TFTP
- Best practice is to pull publisher out of all call processing and let subscribers do the work
- Phones can list 3 redundant CUCM servers for failover purposes
Unity Connection
- Make any message retrievable from any voice enabled device or application
- Supports 20000 voicemail boxes
- Runs as VMware guest
- Active / Active setup, publisher, subscriber
- Features
- Personal call transfer rules, speech recognition
Unity Connection Key Features

- 20k mailboxes per server (cluster?)
- Access voicemail from anywhere
- LDAP integration
- Microsoft Exchange support
- Voicemail Profile for Internet Mail (VPIM)
- Integration of voicemail services from difference vendors
- Active / active high availability
- Publisher / subscriber cluster
- Both accept client requests
- CUCM + CUC communicate using SCCP or SIP

- Industry standard, works with different IM clients
- Message compliance
- Logging
- Encryption with TLS
- Interdomain federation
- Connects to other domains outside of your business
- Business to business communication
- Secure Messaging
- TLS, IPSec
