QoS Enhacements in CUCM 11.X

Image
These were added in CUCM v11The main enhancements are:Separating UDP Port Ranges for Audio and VideoSeparating DSCP Markings for Audio and Video streams in Video Calls You can have separate markings for audio in Telepresence video call than Fixed video callNavigate to Device > Device Settings > SIP Profile. Current endpoints which support this enhancement (03/11/2016)Video Endpoint DSCP for Audio Portion of Video Calls DSCP for Audio Portion of TelePresence Calls 8800 Series Yes N/A 8900 Series No N/A 9900 Series No N/A Jabber Yes (Jabber for Windows uses Group Policy Objects to mark traffic on the PC else DSCP will be set to '0'. All other Jabber clients are able to mark DSCP natively) No DX Series Yes Yes TX Series N/A Yes IX Series N/A No CE 8.x Software Series (SX Series, MX Series G2, MX700, MX800) N/A Yes TC 7.1.4 Software Series (C Series, Profile Series, EX Series, MX Series G1) N/A Yes

Enable DSCP Markings on Windows OS (7, 8, 10)

By default windows OS will set DSCP markings to '0' ignoring the marking settings on the client. This can be good and bad.

A good scenario is to make sure that torrent clients aren't getting priority (while ideally your enterprise network qos policies should overcome this problem as well)

A bad scenario is overriding DSCP markings from Jabber Client which marks packets genuinely  for seperating audio and video streams treatment.

While you can still overcome the problem of Jabber Client using network QoS policies, you can allow QoS marking on windows OS as follow:

1. Go to HKLM\System\CurrentControlSet\Services\Tcpip\QoS. If "QoS" folder doesn't exist there - create it. 2. Add a DWORD parameter named "Do not use NLA" and assign "1" as its value. 3. Reboot.


Notes on Self-Service ID

The Self-Service User ID is generate automatically once the primary extension is assigned to the End UserThe Primary extension can be assigned manually, using LDAP or using BATFor LDAP Self-Service IDs it will be generated during the 1st LDAP sync (not on LDAP update)Self-Service ID will be generated only if the user doesn't have oneFor upgrades from Pre-10.x to 10.x, Self-Service ID will be generated for users with Primary ExtensionsWhen same DN is assigned to multiple partitions and to multiple users as primary extension, Self-Service ID will be made unique by prefixing a code of *01, *02, etcYou can change the Self-Service ID, manually from End User configuration page

CUCM Self-Provisioning

This feature allow end-users or administrators to provision phones with minimum admin workIt was introduced with CUCM 10.xThe users need to follow the prompts on the phones to login to CUCM which will auto-provision the phonesHow it works?The phone auto-registers with CUCMDuring auto-registration it gets an idle URL. This idle URL points the phone to self-provision XPS resource running on CUCMOnce the phone contacts the XPS resource, it will be prompted for user ID/pinFrom here there are two approaches to complete Self-ProvisioningOption#1When the users enter the user ID and PIN, they are authenticated with the CM and their primary extension is determinedThe users are then prompted to confirm that they wish to provision the phone using their primary extension. If they confirm, the phone will be provisioned and resetOption#2The users can call Self-Provision IVRThe users need to enter …
