Hi Cindy,   I think you are seeing this Bug/Enhancement;   Headset Does Not Alert to Incoming Calls on IP Phone CSCvo70826   Symptom: Cisco Headset 500 Series does not play an audible tone when incoming call is received on IP Phone device. This is a known limitation in the Cisco Headset 500 Series, as noted in the following: https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cuipph/Headsets/English/userguide/h56x_b_cisco-500-series-user-guide.pdf Conditions: Cisco Headset 500 Series paired with IP Phone, which receives incoming call event.   Cheers!

Hi Adam,   Yes, the 561 & 562 will provide an audible tone to give the user the ability to answer an incoming call via headset. You would need to configure "headset hookswitch control" on your phone/device in CUCM for this to work properly.   https://www.cisco.com/c/en/us/products/collateral/collaboration-endpoints/headset-500-series/datasheet-c78-740352.html   Cheers!

Hi Marc,   The  CP-8800-V-KEM is not supported on the 8851/61's as they now use the CP-8800-A-KEM and the 8865's use only the V-KEM;   "This means that you cannot mix audio expansion modules with video expansion modules. You also cannot use a video expansion module on an audio phone or an audio expansion module on a video phone."   From;   https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cuipph/7800-8800/english/accessories/p881_b_accessorie-guide-for-cisco-ip/p881_b_accessorie-guide-for-cisco-ip_chapter_01.pdf   You also see the distinction between the two module/models in this doc;   For 8865 deployments please consider the CP-8800-V-KEM=   For 8851/61 deployments please consider the CP-8800-A-KEM=   From;   https://www.cisco.com/c/en/us/products/collateral/collaboration-endpoints/unified-ip-phone-8800-series/eos-eol-notice-c51-741310.html   Cheers!

Hi Joshua,   I think it may actually be this bug;   Cluster reboot needed for device pack in CUCM version 11.5(1) CSCvk22694   Description Symptom: phone showing "none" in registration status in CUCM web page. Conditions: as per documentations: https://www.cisco.com/c/en/us/support/docs/unified-communications/unified-communications-manager-callmanager/213290-configure-device-pack-on-cisco-call-mana.html https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/compat/Devpacks_admin/CMDP_BK_CD82F19C_00_cisco-unified-communications-manager-device/Cisco_Unified_Communications_Manager_Device_Package_Installation_and_Administration.html "When you apply a device package to enable new device support, a cluster-wide reboot is not required for CUCM version 11.5(1) or later. Instead, after you add the device pack, follow this in CUCM Restart the Cisco Tomcat service on all nodes Restart Cisco TFTP on all servers, where this service is running Restart Cisco CallManager on the Publisher. If you're not running the Cisco CallManager service on the Publisher, you can skip this step." however when adding device pack 11.5(1)(15078-1) (cmterm-devicepack11.5.1.15078-1.cop.sgn) into CUCM 11.5(1) SU1, in order to add 8832 Cisco IP Conference Phone, the phone gets registered fine, but it doesn't show up registered in CUCM web page. it looks like following documentation steps doesn't allow for the phone to show up registered. Workaround: Reboot the cluster   Cheers! Rob ... View more

Hi Claudio,   Yes the 210-060 would work for re certification as it is considered an Associate level exam;   CCNA Collaboration certifications are valid for three years. To recertify, pass ONE of the following before the certification expiration date: Pass any current Associate-level exam except for the ICND1 exam https://www.cisco.com/c/en_ca/training-events/career-certifications/associate/ccna-collaboration.html#~Recert   Cheers!

Hi Brent,   The only model that you listed that is nearing end of support is the 7920. It is one of the "Deprecated" models beginning in CUCM 11.5(x);   The following phone models are deprecated and are not supported by Cisco Unified Communications Manager Release 11.5(x). If you are using any of these phone models and you upgrade to release 11.5(x), you will be unable to use the phone after the upgrade. After you switch over to the new release, registration on the phone will be blocked.
