CUCM 10.5 - MGCP w/ BRI not supported with Single Number Reach - Incoming calls to In-Dial Numbers failing when dialing from a Mobile Phone whose number is registered in CUCM as a Remote Destination for Single Number Reach

So we had an issue for months where if Single Number Reach (Mobility Connect Features) were enabled for users and if they would then use their mobile phones to dial in to the in-dial range (company extensions) the calls would fail, they would then have to block their CLID on their mobile phones before making the call for it to work.

Issue: Users having to have to block their caller-id to dial in to the office main line or that their SNR has stopped working all of a sudeen.

CUCM 10.5.2.10000-5

Temp fix: 

The root cause of the issue turned out to be the following:

So we basically had MGCP BRI in our environment with SNR activated. The option to get away from this was to NOT use BRI in your environment if we want to implement SNR function, need to get rid of the BRI MGCP irrespective of whether it's in use or no. 

Cisco developers confirmed that BRI is the source of “CellProxyCdpc” leaking which cause SNR call reaches the limit.  Document “Features and Services Guide for Cisco Unified Communications Manager, Release 10.0(1)” chapter “Cisco Mobility” says:

"Gateways and Ports  Both H.323 and SIP VoIP gateways are supported for Mobile Voice Access.  Cisco Unified Mobility features do not get supported for T1 CAS, FXO, FXS and BRI."

MGCP and BRI is not supported by the SNR feature because  BRI couldn’t tell the SNR process to terminate the call.

Mobile Connect features do not get supported for T1 CAS, FXO, FXS and BRI.

These SNR calls through MGCP GWs cause CellProxyCdpc  process leaked hence the problem

UCCX Data Source Offline - Environment has 3rd Party Wallboard

Had an ongoing issue with the UCCX Data Source going offline and we were using a third party wallboard application... this would result in Agents not being able to view realtime stats on the wallboard.

If you have a similar issue with a similar setup then you would want to rule out any bugs on the CCX (we had to apply a few cop files for what looked like a bug) however finally the issue turned out to be the settings on the 3rd party app ...

Basically Cisco does not support issues if you have a 3rd party wallboard using the UCCXHR User for polling (reading from the CUIC DB), it should use the UCCXWallboard User for it's queries.

• Cisco recommend you don’t poll faster than 5 seconds on uccxwallboard user
• If the timers are too aggressive on the wallbaord app (like every 2 seconds) then you will face UCCX DB crashing issues, the polling timers should be changed to poll every 5 or 10 seconds at minimum
• UCCX is not supported by TAC if a 3rd party wallboard is installed and using the UCCXHRUser as opposed to the UCCXWallboardUser. 

UCCX 11.5 - Second Node Installation Error "Configuration validation with UCCXSRV failed. Configured first node UCCXSRV is not a first node -is UCCXSRV entered correctly? -is UCCXSRV the correct first node for this node"

To summarize: Make sure if you reset the security password on the Publisher (even if it's right) using the procedure below and then try installing again if you hit this error.

Had a nightmare with this issue (both servers on the LAN).

Verified the security password was correct as it tells you when you try to reset it back to the same old password so then after taking log dumps over the serial port and analysing the logs it said the below which meant there was an issue with the security password.

02/23/2018 01:22:30 IPM|(CAPTURE) head: cannot open `/usr/local/platform/.security/CCMEncryption/keys/encrypted_Dkey.txt' for reading: No such file or directory|<LVL::Debug>

02/23/2018 01:22:30 IPM|(CAPTURE) isftp using password failed (15). Trying sftp using keys.|<LVL::Debug>

02/23/2018 01:22:30 IPM|(CAPTURE) Required file /usr/local/platform/conf/platformConfig.xml not present on first node (active)|<LVL::Debug>

02/23/2018 01:22:30 IPM|(CAPTURE) isftp using password failed (15). Trying sftp using keys.|<LVL::Debug>

Procedure

Step 1	Log in to the system with the following username and password: Username: pwrecovery Password: pwreset The Welcome to platform password reset window appears.
Step 2	Press any key to continue.
Step 3	If you have a CD or DVD in the disk drive, remove it now.
Step 4	Press any key to continue. The system tests to ensure that you removed the CD or DVD from the disk drive.
Step 5	Insert a valid CD or DVD into the disk drive. Note    For this test, you must use a data CD, not a music CD. The system tests to ensure that you have inserted the disk.
Step 6	After the system verifies that you have inserted the disk, you are prompted to enter one of the following options to continue: Enter a to reset the Administrator password. Enter s to reset the security password. Enter q to quit.
Step 7	Enter a new password of the type that you chose.
Step 8	Reenter the new password. The password must contain at least six characters. The system checks the new password for strength. If the password does not pass the strength check, you are prompted to enter a new password.
Step 9	After the system verifies the strength of the new password, the password is reset. You are prompted to press any key to exit the password reset utility.

So used the above procedure to change the Security Password on the Publisher and rebooted the node, then went over the install again and it went through fine (did ask me for "more time") but ultimately went through fine. 

Then tried installing a .cop file to math what's on the publisher and hit the following bug so had to restart the install from the CLI and all good.

Attempted to upgrade the system to ES03 but we ran into the defect:

Cisco CCIE Collaboration Bootcamp - Sept 10 - Nov 15, 2016

CCIE COLLABORATION LAB TOPOLOGY

COURSE DESCRIPTION

Although the CCIE Collaboration is not very much different than it's predecessor the CCIE Voice Lab you still need some new equipment (PVDM3-128 and Cisco 2911 Voice Gateways along with the CP9971CL) besides the telepresence products to work on every aspect of the lab....

This will be my first batch in Sydney, Australia having conducted more than 20 Cisco Bootcamps in the Middle East (Saudi, Dubai), having tutored close to 100 students and helped CCIE Certify 10-20 students. I've been taking CCIE Voice/Collab Classes since Nov 2008, (Voice, Collab and DataCenter) and this would be my 1st batch in Australia, each batch normally consists of an average of 8 students (min of 6 and max of 12).

Book a Class: 

All those interested may confirm their seats up to a week prior to the scheduled start date of Sept 10, 2016, a seat can only be confirmed with an advanced payment of AuD 600/- (balance fee of AUD 2000/- to be paid a week before the course starts)

** Do keep in mind that all payments made are non-refundable.

Course Details: This is a complete hands-on course with all concepts explained and demonstrated practically, we will cover the core CCNA, CCNP and CCIE Collaboration topics with emphasis on the CCIE Collaboration Lab, although this course will not cover each and every CCNA, CCNP topic it will definitely cover the core topics that would get you ready for the CCIE COLLAB LAB.

The Equipment we'll be working on is as per the CCIE Collaboration Lab Blueprint and is a complete lab with all the equipment matching the CCIE Collaboration Lab requirements except we'll be using the ISM-300 instead of the SRE-710 running code 8.6, the PSTN and Site B would be a 2911 Voice Gateway while the HQ and Site C would have a 2921 Voice Gateway, PVDM3-128 would be present to test Video Conferencing, besides this all the Application Servers are running on VM and you'll have three Cisco 9971 Phones for testing Video.  A complete BoQ with snaps of the class can be found on my LinkedIn profile or you may visit my blog @ ipninjas.blogspot.com, you may as well shoot me an email.

Duration of the Course: Between 45 - 70 days depends on the number of breaks we take!!, ideally the class gets over in roughly 60 days.

Class Timings: Classes will be thrice a week after (timings to be confirmed with all students in the batch), each class would roughly span 2-4 hours, the class would be recorded and you may take the recordings for your future reference, 1 day of the week would be hands-on only.

Note: If you do happen to pay the fee and are unable to join for whatever reason then you are most welcome to join another batch (based on seat and class availability ) free of charge but bear in mind a refund is not an option. Once the course is over you may as well join another batch (subject to availability of a seat) for free to revise concepts.

Class Room: The batch would consist of a maximum of 12 students and a minimum of 6 students.
