Cisco Unified Communications Manager (2024)

FAQs

How many Cisco Unified Communications Manager servers can be listed in a Cisco Unified CM group? ›

Cisco Unified CM Groups Overview. A Unified Communications Manager Group is a prioritized list of up to three redundant servers to which devices can register.

Unified CM is the core of Cisco's collaboration infrastructure. It is an IP-based communications system that allows you to contact your coworkers or customers through audio or video regardless of physical location. The primary function of CUCM is call processing and phone registration.

Default is a system administrator with username Admin and no password.

The voicemail pilot number in CUCM will send the call over to CUC, either via SIP Trunk or via a SCCP-based Hunt Pilot (depending on your integration). Once a call reaches CUC, CUC uses the Call Routing Rules to determine what to do with a call.

A cluster consists of one publisher and a total maximum of 20 servers (nodes) running various services, including TFTP, media resources, conferencing, and call processing.

Maximum Number of Calls - You can configure up to 200 calls for a line on a device, with the limiting factor being the total number of calls that are configured on the device. As you configure the number of calls for one line, the calls that are available for another line decrease.

How much does an Unified Communications Engineer make? The estimated total pay for a Unified Communications Engineer is $110,518 per year, with an average salary of $87,884 per year.

A Cisco Unified Call Manager (CUCM) is, as the name implies, a system of Unified Communications. It features IP telephony for both voice and video calls, as well as unified and instant messaging. With its own mobile app, it's ready to be used by all your workers no matter how remote they may be.

Because UCCX is a more advanced solution with omnichannel contact centre features, the licenses understandably cost more than CUCM licenses. Therefore your spending is instantly reduced. It is also likely in some cases that businesses already pay for CUCM as well as UCCX licensing for some or all of their employees.

The default value is admin.

How do I restart Cisco Unified Communications Manager? ›

Step 1 From the Cisco Unified Communications Operating System Administration window, navigate to Settings > Version. The Version Settings window appears, showing the software version on both the active and inactive partitions. Step 2 Click Restart to restart the system, or click Cancel to stop the operation.

Each Cisco UCS instance has a default user account, admin, which cannot be modified or deleted. This account is the system administrator or superuser account and has full privileges. There is no default password assigned to the admin account; you must choose the password during the initial system setup.

The voicemail pilot number designates the directory number that you dial to access your voice messages.

Cisco Dialed Number Analyzer allows analysis of inbound and outbound calls in a Cisco Unified Communications Manager dial plan. It analyzes the calls and provides results that show complete details of calls, including call patterns and calling and called party transformations that are applied to the dialed digits.

Yes you can use the same VG from two CUCM as long as it is H323 or SIP and you will need some additional dial-peers to send/receive calls from new CUCM.

You cannot have more that 128 rules in an ACL. You cannot have more than 10,000 ACLs (spread across all the ACLs) in one VEM. The following restrictions apply to ACLs: You cannot apply more than one IP ACL and one MAC ACL in each direction on an interface.

What is the difference between UCCE and UCCX? the biggest difference is the capacity; UCCX is more compact and can go up to 400 agents. However UCCE or PCCE can go up to 60,000 or more.

In theory the maximum number is 10,000. That assumes the node has no other responsibilities of any kind other than call processing for phones. As @Elliot Dierksen mentioned the number of devices also depends on the OVA. The maximum devices which a CUCM node can register is 10K.
