This document answers frequently asked question about some of the feature support for the Cisco Unified Communications Manager versions 5.x, 6.x,7.x, and 8.x.
Refer to Cisco Technical Tips Conventions for more information on document conventions.
Q. Is it possible to control the quota for outside calls with Cisco Unified Communications Manager?
A. Call quota control can not be done through the Cisco Unified Communications Manager. It requires a separate third-party application.
Q. How many calls can be handled by a non gatekeeper controlled Inter-cluster trunk (ICT)?
A. The ICT handles the same number of calls that the Cisco Unified Communications Manager server can handle, which depends on the capacity of the server and the bandwidth available.
Q. Does Cisco Unified Communications Manager support the Dictation feature?
A. No. Dictation is not currently a Cisco Unified Communications Manager feature.
Q. Can I add multiple pilot points and hunt group members through Bulk Administration Tool (BAT)?
A. No, it is not possible to add multiple pilot points and hunt group members through BAT.
Q. How do I filter users based on the IP Phone attribute?
A. This is only possible through scripts or if you adjust the user rights on the LDAP system.
Q. Can I use BAT to update users when integrated with LDAP?
A. No, BAT cannot be used to update users when integrated with LDAP. You must disable LDAP integration, make the changes through BAT, and then re-enable LDAP.
Q. Does Cisco Unified Communications Manager support Calling Line Identification (CLID) with an analog port and an MGCP Gateway?
A. Cisco Unified Communications Manager 7.0 does not support CLID with an analog port and MGCP Gateway. You must use either an H323 or a SIP gateway.
However, this is supported in Cisco Unified Communications Manager 8.0(1) and later. Refer to Cisco Unified Communications Manager Administration-Caller ID Support on MGCP FXO Gateways for more information.
Q. With Cisco Unified Communications Manager 7.x, is it possible to allow end users to change the Speed Dial BLF configuration through the Cisco Unified Communications Manager User page?
A. In the Cisco Unified Communications Manager 7.x environment, only the system administrator can configure a BLF speed dial. A system user is not allowed to configure a BLF speed dial.
Q. Is it possible to conference another party after Single Button Barge?
A. This is only possible in C Barge, as C Barge only has the access to a Built-In Conference Bridge.
Q. Is it possible to pull a report from Cisco Unified Communications Manager version 7.0 that includes the actual minutes of talk time?
A. Complete these steps:
- Open the Cisco Unified Communications Manager Serviceability web page.
- Choose Tools > CDR Analysis and Reporting > User Report > Top N > by Duration > Available Reports > Generate new report.
- Select the date range.
- Click View Report.
Q. Is there is a way to get the Serial Numbers of 7960/40 phones on the Cisco Unified Communications Manager with SNMP?
A. This is not possible because the IP Phone does not support SNMP. This information is not stored in the SQL database that Cisco Unified Communications Manager uses. Cisco Unified Communications Manager does not use the serial numbers for anything, so it has no need to store them. There are three ways to get the serial number of the phone:
Get the serial number from the HTTP interface on the phone HTTP://Phone.IP .Address/.
Read the serial number off the phone physically.
Contact your local Cisco account manager.
Q. Does Cisco Unified Communications Manager 7.x support HP Insight Manager?
A. Unfortunately, HP Insight Manager is not supported on Linux based Cisco Unified Communications Manager servers (5.x, 6.x, 7.x and 8.x). It is only supported on Microsoft Windows based Cisco CallManager servers (3.x and 4.x). You can use HP ILO to monitor Linux based Cisco Unified Communications Manager servers.
Q. How do I change the codec used for internal calls (extension to extension) from G.722 to G.711?
A. If the regions already talk G.711, but the phones advertise G.722, choose System > Enterprise Parameters > Advertise G.722 Codec > Disabled.
Note: This can also be done individually at the phone level.
Q. How do I setup a secure TLS and SRTP SIP trunk between Cisco Unified Communications Manager cluster?
A. Complete these steps to setup a secure TLS and SRTP SIP trunk between Cisco Unified Communications Manager cluster:
Create a new SIP Trunk Security Profile from System > Security Profile > SIP Trunk Security Profile. Make sure you Device Security Mode set to Encrypted and the incoming/outgoing transport type set to TLS.
Apply this security profile to your SIP trunk, and set the destination port to 5061.
Download the Cisco Unified Communications Manager certificates from all servers in the Cisco Unified Communications Manager group configured on the SIP trunks device pool, and upload them to the servers of the other cluster. Record which servers are in ClusterA from SIP Trunk > device pool > Cisco Unified Communications Manager group. There can be up to three. Do the same for ClusterB. The results are something like this.
Go to the OS Administration page of each server in your list and login.
Go to Security > Certificate Management, and click Find. Locate the Certificate Name column and find the CallManager certificate not the CallManager-Trust certificates. Click the .pem link on the right of the name, and click the download button. This is how you save the certificate from each server.
Once you download all the needed certificates (all servers certificates from both clusters), upload them to the other cluster. Upload the certificates of Server 1, 2, and 3 from ClusterB to ClusterA Server 1. Repeat this for ClusterA Servers 2 and Server 3. On ClusterB Server1 upload the certificates from ClusterA Server 1, 2, and 3. Repeat this for ClusterB Servers 2 and 3. Go to the same Certificate Management page for each of these, and click Upload Certificate. This time, select the CallManager-Trust certificate type. After all the certificates are uploaded to each of the servers in the opposite cluster, restart the CallManager service on all servers to which you uploaded the certificates .
Edit the SIP Trunk security profile again. Find the X.509 Subject Name field. On ClusterA, enter the subject CN of each ClusterB Server1, ClusterB Server2, and ClusterB Server3 in that field exactly as it appears in the certificate. Separate the names with a space, comma, semicolon, or a colon. Go to ClusterB, edit the SIP Trunk Security Profile, and add the subject names from the certificates of all ClusterA servers too.
Q. How do I configure Barge?
A. Barge allows a user to get added to a remotely active call that is on a shared line. Remotely active calls for a line comprise active (connected) calls that are made to or from another device that shares a directory number with the line.
Refer to these documents for information on how to configure Barge:
Q. How is the extension out of service error resolved when a user tries to log in?
A. This can occur if the end user account is not assigned as CTI enabled. Therefore, make sure that CTI enabled is assigned for the end user.
Q. How does the LDAP synchronization occur in Cisco Unified Communications Manager 7.x?
A. Refer to LDAP Synchronization for information about LDAP synchronization in Cisco Unified Communications Manager 7.x.
Q. Where do I modify the default recipients of the Cisco Unified Communications Manager CDR Reports?
A. Choose CCMAdmin > User Management > End User and select the user for which you want to receive the report. In the Permissions Information section at the bottom of the page, remove the Standard CAR Admin Users group.
Q. Attendant console cannot connect to Cisco Unified Communications Manager 7.x and shows the "Unable to connect to server" error message. How do I troubleshoot this issue?
A. Attendant console is not supported on 7.x and later with a new install. You need to use the CUBAC/CUDAC/CUEAC licensed servers to use Attendant console with 7.x new install. However, Attendant console is supported with 7.x if this is an upgrade from previous versions such as 5.x or 6.x. It is also supported with all versions of 5.x and 6.x whether it is a new install or upgraded.
Q. Is there a way to change the frequency in which the CDR file is sent to the FTP billing server?
A. By default, Cisco Unified Communications Manager pushes out the CDR files to a billing server once they are created. A workaround for this is to change the CDR File Time Interval Enterprise Parameter as this parameter determines how often the files are created.
Q. Is it possible to disable CCMUSER access on some of the CUCM servers without disabling CCMADMIN?
A. Currently, it is not possible to disable CCMUSER access for a specific server.
In order to disable CCMUSER access for a specific user, do not associate the user to these groups: Standard CCM End Users and Standard CCM Admin Users. The user will still be able to see the CCMUSER web page, but will not be able to login to the page. If you do not add the user to these groups, the user cannot view and update the Cisco Unified CM User Options.
Q. How do I find the process names for the critical services that are running in Cisco Unified Communications Manager 7.1?
A. You can issue the show process list command using an SSH connection to the server. This will show the PID and the process with the path. This table shows the mapping of some of the critical services in CUCM 7.1 with their actual process names:
